Firefox Home is a mobile iOS app from the Mozilla Organization. It’s basic function is to give you mobile access to your Firefox Internet Browser History, allowing you to open tabs and bookmarks on your iPhone or iPad.

With its mobile Awesome Bar, you won’t have to retype long URL addresses or spend time on Google searching for your favorite websites. To top it all off, Firefox home comes with a locking feature that allows you to access your data only by entering an encrypted password.

Firefox Home works directly with Firefox Sync, so you’ll have to download and restart Firefox first. As soon as you finish that, you’ll have to connect Firefox Home to your Firefox Sync account. I’ll be walking you through the set up process as it does get a little tricky for some users and then show you how to use all the Firefox Home features.

How to Set Up Firefox Home on your iPhone or iPad

• Set up Firefox Sync on your computer
• Get the easy setup code from Firefox Home
• Connect Firefox Home to your Sync account

How to Use Firefox Home on your iPhone or iPad

• Searching your bookmarks, history and tabs
• Searching the web or going directly to websites
• Accessing your open tabs
• Accessing your bookmarks
• Using the integrated web viewer
• Update your information in the Settings section

Set up Firefox Sync on your computer

Open Firefox on your computer. If you haven’t already, download Firefox and then import your bookmarks and internet history from your previous Internet browser. Click on the Firefox button at the top of the Firefox window (Tools menu in Windows XP). Next click Options, and in the Options window, click on the Sync Tab.

Click Set Up Firefox Sync.

Click Create a New Account.

Here you’ll need to enter your email address, create a password and then confirm it. Once you finish that, check “ I agree to the Terms of Service and Privacy Policy” and select Next.

You will be provided with a Recovery Key. The Recovery Key is use to secure your data before it’s sent to Mozilla’s servers. Think of it as a key that locks away all your personal information in a safety deposit box that only you can open, and Mozilla’s servers are the bank where the box it held. Just like at a bank, this means that neither Mozilla or anyone else can access your “vault” of information without first having access to your Recovery Key to unlock it. This is a really good time to make a note of your key and store it in a really safe place. When you’re finished, click Next.

Confirm that you’re not a robot by enter the text found on the image. (Those things are always impossible to read I know). But try your best, and then click Next.

You’ll be greeted with a Setup Complete! message. Click Finish to close the setup window and take you back to the Sync panel.

There’s nothing else you have to do on your part. Firefox Sync will now automatically synchronize all of your browser data in the background from here on.

You’re first sync should be rather quick, especially if you just download Firefox. But it could take some time if depending on how much information has to be uploaded.

Get the easy setup code from Firefox Home

Download Firefox Home from the App Store, launch the app, and then tap on I Have a Sync Account.

The twelve character code to add this device will be displayed.

Connect Firefox Home to your Sync account

Here you’ll have to enter the setup code on your Firefox browser to connect Firefox Home to your Sync account.

To do this, first go to the default Mozilla Firefox home page.

At the bottom of Firefox’s home page, click the Sync link to open the Sync settings window.

Next click the Pair a device link and the Firefox Sync Setup window will open.

Enter the twelve character code created on your iOS device and click Next.

As soon as the code is accepted you will see a Device Connected message and your device will automatically begin to sync over all of your Bookmarks, Tabs, and Internet History.

Note: If you’re not near a computer, you can still add Firefox Home to your Sync account by simply entering your account information. From Firefox Home’s Connect to Sync screen, tap on I am not near my computer… Next, enter your email address, password,  and recovery key and then enter the information.

Searching your bookmarks, history and tabs

This is exactly like having the Firefox Awesome Bar right on your iPhone or iPad.

If you aren’t already exploring the search tab, Launch Firefox Home and then just tap on the search button at the bottom of the Firefox Home app window.

Tap on the search bar at the top of the window and the keyboard will come up.

To search through your various bookmarks, open tabs, and Internet History, just begin typing the first few letters of the website you’re trying to find.

As soon you start typing, Firefox Home will begin displaying all of its related results.

The results will indicate if they’re a bookmark, an open tab or a history item with an appropriate icon on located the left.

Usually, just two or three letters of a word will get you to the results you want.

To visit a link, just tap on the listing in the search results. It’s that easy.

To then go back to your search results, you can tap on the Home button located at the top of the window.

Searching the web or going directly to websites

If you want to visit a site, but it’s not in your bookmarks, tabs or Internet History, don’t worry! We can still get there.

Go ahead and tap on the search button again at the bottom of the Firefox Home app window.

Tap in the search bar at the top of the window and the keyboard will come up again.

Type in the name or address of the website you want to go to.

If you type in the complete address or if the word you entered matches a top domain, clicking the link that’s displayed will take you right to the website. If Firefox Home can’t find a match for what was entered then the app will simply take you to the Google search results.

If you want to then go back to the previous screen, tap the Home button at the top of the window.

Accessing your open tabs

Working on some Internet research and want to pick up where you left off with access to the tab you had open on your computer? No problem.

Tap the Tabs button at the bottom of the app window and all of your open tabs will then be listed.

To visit a site on your tabs, just tap on its listing.

To return to your open tabs, tap the Home button at the of the window.

Accessing your bookmarks

Now you can have access to all of your favorite Firefox bookmarks without being stuck having to just use the Safari App on your iPhone or iPad. Neither do you have to keep typing in all of those long URL addresses. You don’t even have to type anything in at all. All of your Firefox bookmarks are synced right here.

Tap on the Bookmarks button at the button of the app window and all of your bookmarks will be listed.

The bookmarks toolbar will be listed first followed by your bookmarks menu and then you unsorted bookmarks.

To visit one of your bookmarked websites, just tap on its listing.

To return to your bookmarks, tap the Home button at the top of the window.

Using the integrated web viewer

Once you’ve selected a website, it will open in the iPhone’s integrated web viewer. The controls are at the bottom of the web viewer window.

For your convenience, there are back and forward arrows for navigating through all of the websites you’ve opened.

There is also a reload button to refresh the current page as well.

Finally, there is an export button that lets you view the current website in Mobile Safari, Email the website’s URL using the iOS Mail app, or copy the URL.

To return to Search, Bookmarks or Tabs, tap on the Home button at the top of the window.

Update your information in the Settings section

Every time that you launch Firefox Home it will update its copy of your bookmarks, history and tabs from your Firefox Sync account. If, for any reason, you need to make Firefox Home update your information while you’re still using the app, just tap on the Refresh button in the Setting section.

If you’re having some problems seeing your information in Firefox Home, one thing you could do is a full refresh of your data.

In Firefox Home, tap on the Settings icon at the bottom of the window and then tap the Sign Out button at the top of the window.

Click the Sign Out button again and you will be presented with a log in screen.

Enter you Firefox Sync username or email address, and password to log in and automatically refresh all of your data.

Mozilla Firefox’s Web Developer menu has tools for inspecting internet pages, running JavaScript code, and viewing HTTP requests and other relevant messages. In this tutorial you’ll learn about Firefox’s all-new Inspector tool and updated Scratchpad.

Mozilla Firefox’s new web developer features, combined with top of the line Firefox web developer addons like Firebug and Web Developer Toolbar, make Mozilla Firefox the ideal internet browser for web developers. All of these tools are available absolutely for free under Web Developer in Firefox’s menu.

Page Inspector

You can inspect a specific element’s code by right-clicking it and selecting Inspect (or by pressing Q on your keyboard). You can also launch the Inspector right from the Web Developer menu.

You will then see a toolbar at the bottom of the webpage, which you can then use to control the Inspector and check out all the elements on the page. Your selected element will be highlighted and other elements on the webpage will be dimmed out.

If you want to select a new element on the page, click the Inspect button on the toolbar, hover your mouse over the page and click you element. Mozilla Firefox will then highlight the element under your cursor as you maneuver it across the page.

You can also go back and forth between parent and child code elements by clicking the breadcrumbs on the Inspector toolbar.

HTML Inspector

Click on the HTML button to view the HTML code of your selected element.

The HTML Inspector will allow you to expand and collapse the HTML tags, making it easy to visualize your changes right on the page – very similar to WYSIWYG software like Adobe Dreamweaver.

If you want to see the webpage’s HTML in a flat file, you can also select View Page Source from the Web Developer Menu. (Remember to bring up the Web Developer Menu just use your cursor to right-click anywhere on the webpage).

CSS Inspector

Click on the Style button to see the CSS rules that are being applied to the selected element and there’s also a CSS Computed panel.

You can switch between Rules and Computed by clicking the Rules and Computed buttons. To help you find specific CSS properties, the computed panel includes a search box.

You can also edit the element’s CSS straight from the Rule panel. Uncheck any of the check boxes to temporarily deactivate the rule, click the text to change a rule, or add your own rules to the element at the top of the panel. Here, we’ve added the font-weight: bold CSS rule, making the element’s text bold.

JavaScript Scratchpad

The Scratchpad also saw an update with recent versions of Firefox, and it now contains syntax highlighting. You can type in JavaScript code to run on the current webpage.

As soon as you have, click the Execute menu and then select Run. The code runs in the current tab.

Web Console

The new Firefox Web Console replaced the old Error Console, which has been belittled by users and removed by Mozilla developers in the latest versions of Firefox.

The Web Console displays 4 different types of messages, which you can then toggle the visibility of – network request, CSS error messages, JavaScript error messages and web developer messages.

A web developer message is a notification printed to the window.console object. For example, you could run the window.console.log (“Hello World”); Javascript code in the Scratchpad to print a developer message to the console. Web developers can integrate these messages into their JavaScript code to help with debugging.

Refresh the webpage and you then see the generated network requests and other related messages.

Use the search box to filter the messages; click a request if you want to see more details.

With recent versions of Firefox, the Web Console can work in tandem with the Page Inspector. The $0 variable stands for the currently selected object in the Firefox Inspector. So, for example, if we wanted to hide the currently selected object, you could run $0.style.display=”none” in the console.

If you are interested in learning more about using the Web Console and its various built-in functions, check out the Web Console page on Mozilla’s Developer Network website.

But when you look under the hood, and there are a number of hidden tips and tricks available that will crank the browser up for you – making it faster, easier, and more efficient to use.

Here are 10 really awesome Firefox tricks you can apply right now:

1. Add more screen space by making you icons smaller – Go to View >> Toolbars >> Customize and check the “Use small icons” box.

2. Use Smart Keywords – If there is a search term you enter a lot, this is a great tool that not many people take advantage of. Visit your favorite search engine, then right-click on the search box. Select “Add a Keyword for this search” give the keyword a name and an easy-to-type and easy-to-remember shortcut name and save it. Now, when you want to do a search for that term, go to Firefox’s address bar, type the keyword and press return. Instant search! You can do this with any search engine.

3. Keyboard shortcuts – It may take a little bit of time to master all of these, but as soon as you do, your browsing will be a lot faster – not to mention you won’t have to use a mouse anymore. Here are some of the most popular keyboard shortcuts for Firefox.

• Spacebar (page down)
• Shift-Spacebar (page up)
• Ctrl+F (find)
• Alt-N (find next)
• Ctrl+D (bookmark page)
• Ctrl+T (new tab)
• Ctrl+K (go to search box)
• Ctrl+L (go to address bar)
• Ctrl+= (increase text size)
• Ctrl+- (decrease text size)
• Ctrl-W (close tab)
• F5 (reload)
• Alt-Home (go to home page)

4. Auto complete – Here’s another keyboard shortcut, but less known and even more useful. Go to the address bar (Control-L) and type the name of the website without the “www” or the “.com” Let’s say “google”. Then press Control-Enter, and it will automatically fill in the “www” and the “.com” and take you there – like magic! For .net addresses, press Shift-Enter, and for .org addresses, press Control-Shift-Enter.

5. Tab Navigation – Instead of using the mouse to select different tabs that you’ve opened, use your keyboard! Here are the shortcuts for that:

• Ctrl+Tab (rotate forward among tabs)
• Ctrl+Shft+Tab (rotate to the previous tab)
• Ctrl+1-9 (choose a number to jump to a specific tab)

6. Mouse shortcuts – Sometimes you are already using your mouse and it’s just a lot easier to use a mouse shortcut than to switch over to your keyboard. Check out these really cool tricks for your mouse on Firefox:

• Middle click on link (opens in new tab)
• Shift-scroll down (previous page)
• Shift-scroll up (next page)
• Ctrl-scroll up (decrease text size)
• Ctrl-scroll down (increase text size)
• Middle click on a tab (closes tab)

7. Delete items from address bar history – Mozilla Firefox’s ability to automatically show previous URLs you’ve visited, as you type, in the address bar’s drop-down history menu is very cool. But sometimes you just don’t want those URLs to show up. Go to the address bar (Ctrl-L), start typing an address, and the drop-down menu will appear with the URLs of pages you’ve visited with those letters in them. Use the down-arrow to go down to a web address you want to delete, and press the Delete key to make it gone for good.

8. Add a keyword for a bookmark – Go to your bookmarks a whole lot faster by giving them keywords. Right-click the bookmark and then select Properties. Put a short keyword in the keyword field, save it, and now you can type that keyword in the address bar and it will immediately go to that bookmark.

9. Speed up Firefox – If you have a broadband connection, you can use pipelining to speed up you page loads. This allows Firefox to load multiple things on a page at once, instead of one at a time (by default, it is optimized for dialup connections). Here’s how you do it:

• Type “about:config” into the address bar and hit return. Type “network.http” in the filter field, and change the following settings (double-click on them to change them):
• Set “network.http.pipelining” to “true”
• Set “network.http.proxy.pipelining” to “true”
• Set “network.http.pipelining.maxrequests” to a number like 30. This will allow it to make 30 requests at once.
• Also, right-click anywhere and select New-> Integer. Name it “nglayout.initialpaint.delay” and set its value to “0″. This value is the amount of time the browser waits before it acts on information it receives.

10. Limit RAM usage – If Firefox is taking up too much of the memory on your computer, you can limit the amount of RAM it is allowed to use. Go to about:config, filter “browser.cache” and select “browser.cache.disk.capacity”. It’s set to 50000, but you can lower it, depending on how much memory you have. Try 15000 if you have between 512MB and 1GB ram.

You can also reduce RAM usage even further for when Firefox is minimized. This setting will move Firefox to your hard drive when you minimize it, taking up much less memory. And there is no noticeable difference in speed when you restore Firefox, so it’s definitely worth a go. Again, go to about:config, right-click anywhere and select New-> Boolean. Name it “config.trim_on_minimize” and set it to TRUE. You have to restart Firefox for these settings to take effect.

Mozilla Firefox includes many powerful features to prevent you from being tracked online, but they aren’t on by default. We’ll show you how to take control of your privacy online with Firefox’s options.

Firefox Internet Browser has some features that send personal data to Mozilla and Google, but these features aren’t required. Mozilla and Google use the date to improve Firefox, provide you with search suggestions and block malicious websites.

Firefox “Do-Not-Track” Feature

Firefox can send a “do-not-track” whenever you connect to a website, asking the website not to track you. It’s disabled by default, so you’ll have to turn it on yourself.

Select the Firefox menu, click Options and then the Privacy icon.

Click the “Tell websites I do not want to be tracked” check box at the top of the privacy pane to enable the do-not-track feature.

Unfortunately, few websites obey your do-not-track preference at the moment. Do not track is also available in Internet Explorer 9 and Apple Safari, but it’s noticeably absent in Google Chrome.

Search Suggestions

Firefox sends every letter you type into its search box to your default search engine, which sends search suggestions back.

You can easily disable search suggestions by right-clicking the search box and unchecking Show Suggestions.

Safe Browsing

Firefox uses the same phishing and malware detection technology found in Google Chrome. Like Chrome, Firefox automatically downloads an updated list of malicious websites from Google every 30 minutes. If you try to access one of these websites, Firefox sends contacts Google to confirm the website is malicious.

It shouldn’t be possible for Google to determine the exact website you tried to access, but Google cookies you have on your computer may also be sent. Phishing and malware detection helps protect your personal data and your computer’s security, but you can disable it using the options on the security pane.

Cookies

Click the “Firefox will” box on the privacy pane and select “Use Custom Settings for History” to view Firefox’s cookie options.

Many advertising networks track you across multiple websites with third-party cookies. You can disable these cookies by unchecking the Accept third-party cookies box. This may cause problems with some websites, so you may have to re-enable this check box.

First-party cookies can be used for tracking, too. Many websites won’t work if you disable cookies entirely, but you can have Firefox automatically clear them each time you close your browser. This prevents websites from building up a profile of you over time, but you’ll have to log into any open websites each time you reopen Firefox. Just enable the “Clear history when Firefox closes” check box and click the Settings button.

Select Cookies and any other type of data you want Firefox to automatically delete, and then click OK.

Crash Reports and Performance Data

Firefox can send crash and performance reports to Mozilla. Mozilla uses these reports to fix problems and help improve Firefox.

The Submit crash reports check box on the advanced pane controls the crash reports feature. Firefox never sends crash reports automatically; it always prompts you. You’ll still see the prompt if you uncheck this check box, but the crash report dialog will default to not sharing any data with Mozilla.

The Submit performance data option causes Firefox to send anonymous performance reports in the background. The reports contain information about how you use Firefox’s interface, how well Firefox is performing and what hardware your computer contains.

Remember to save your settings by clicking OK.

The Mozilla Firefox Internet Browser does a fantastic job of saving your usernames and passwords so you don’t have to remember them next time you visit a website. While this feature is a great tool, Firefox doesn’t include a good backup method to save passwords and user accounts in case you need to restore or copy them to a safe location. You can backup your entire Firefox directory, but if you just want to keep a backup copy, or you need to sync them with another computer, the Firefox extension Password Exporter is all you need.

How to Export Saved Passwords Out of Firefox

The Firefox add-on Password Exporter lets you export and import you saved usernames, passwords, and disabled login hosts between computers or just to keep as a backup copy. All of your saved passwords will be exported to an XML or CSV file and can be encrypted for protection.

To install Password Exporter go to Tools >> Add-ons. Search for Password Exporter, click on “Install Now”, follow the instructions, and then restart Firefox after the installation is completed.

Access Password Exporter from Tools >> Options and select the Security Tab.

Locate the “Import/Export Passwords” button in the Saved Passwords section:

To export, click on the “Import/Export Passwords” button and select “Encrypt Usernames/Passwords” check box (recommended for security purposes) then click on “Export Passwords”.

To save the file, give it a name and select to either save it as a XML or CSV file.

Once saved, you can back it up or import it to another Computer running Firefox with Password Exporter installed.

This is NOT to be confused with Internet Explorer Tab Groups. That… that would just be wrong.

Why you should use Tab Groups

If you have enough tabs that it’s borderline ridiculous, then Tab groups might just be for you. If you’re regularly ending up with more tabs than fit on the Tab Strip, then Tab groups could be right up your alley. If you’re constantly going a hundred miles a second on the internet to get through your crazy work day, then you’d better listen up.

How to Create a Tab Group / How to Navigate through Tab Groups

You should already have a number of tabs to work with but if you don’t, go ahead and open a few now.

1.) Enter the Tab Groups view by clicking the List All Tabs button at the far right of the Tab Strip. It doesn’t say ‘All Tabs’ so look for the button with an arrow in the middle pointing down. Press Ctrl + Shift + E for the shortcut.

2.) When you enter the Tab Groups view for the first time, you’ll see thumbnail previews of all of your tabs in one group. To make a new group, simply drag one tab out of the group and then drag a second one on top of it. A box will be drawn around them.

3.) When you are done, just click on a tab to exit the view. You will be returned to Firefox, the tab you clicked on will be active and only the tabs in that group will be visible.

4.) Click on a tab in the group you want to switch to and you’ll exit the view and be returned to Firefox. The tab you clicked on will be active and only the tabs in that group will be visible.

5.) Click the search button on the right side of the window to bring up the search box and then just begin typing the name of the tab you’re trying to find.

6.) As you type, the tabs that match your search will be highlighted. Just click on a tab to select it and be returned to Firefox.

Yeah I'd rather stick with Firefox

App Tabs is a cool feature by Mozilla Firefox that lets you always keep your most visited web sites like Facebook, Twitter and Gmail open in miniature tabs. Apps tabs open automatically each time you launch Firefox and can’t be closed by accident. In this tutorial we will show you how to make and use Firefox App Tabs.

Why you should use App Tabs

Firefox App Tabs allow you to pint any website to the left side of the Tab Strip so that it’s always available, loaded, and ready. In this way, you can receive notifications from websites like Twitter, Facebook, and Gmail without even breaking a sweat. It helps too if you’re like me and periodically late to work (almost every day) and need your company’s clock in website open and ready when you launch the internet browser.

Or it could just save you the refresh…

Typical day at the office

How to make an App Tab

Right-click on the tab you want to keep as an App Tab and select Pin as App Tab from the menu.

How is App Tabs different than a regular tab or a bookmark?

- App Tabs don’t have a close button so they are always open and you can’t close them by accident.

- They notify you with a blue highlight when you receive new data on the site like an email, comment or message.

- All the App Tabs will automatically launch each time you launch Firefox, so you don’t have to wait for it to load like a bookmark.

- When you open a link in App Tabs, it’ll automatically open in a new tab so your App Tabs stay on the same page.

- App Tabs are smaller and out of the way.

Mozilla Firefox provides useful, customizable toolbars that provide easy access to common features and sites. In this tutorial we’ll show you how toolbars can be displayed or hidden depending on your preferences.

1. Open the Mozilla Firefox Internet Browser. On the top, you’ll notice a menu bar that says File, Edit, History, Bookmarks, Tools and Help. Next to that is an empty section known as the Tab Strip.
2. Right-click the Tab Strip. The menu will display various toolbars with or without check marks next to them:

• Menu Bar – This is your most basic Firefox toolbar that displays the browser menus File, Edit, View, History, Bookmarks, Tools, and Help. If you choose to keep the menu bar hidden, you can always temporarily show it by pressing the Alt key.
• Tab Strip – This is the section where your web page tabs are displayed. You cannot remove the tab strip, but you can rearrange it to be above or below the Navigation Toolbar. To do this, right-click the tab strip and check/uncheck Tabs on Top.
• Navigation Toolbar – This is your web address toolbar. It contains your web site navigation buttons, the location bar, the search bar, the home button and the bookmarks button.
• Bookmarks Toolbar – Contains your bookmarks and bookmark folders.
• Add-on Toolbar – this toolbar is associated with your Firefox extensions and is located at the bottom of the Firefox window.
