Firefox Personas, the lightweight themes for the Firefox browser, are still pretty new to the Mozilla user base our there. 
With that in mind, I thought it might be handy to guide you through the process when it comes to adding a new Persona theme to your browser, removing a Persona theme from your browser, and how to chance through Persona themes – once you have several saved to your system.

The master password in Firefox is used to add another layer of security to your password system.  What would happen though if you setup a master password, got in an accident, were in a coma for six months, and then once you awoke you couldn’t remember what your master password was set to?  I’ll help you reset or recover your Firefox master password with one simple tool.

Out of user demand, I have decided to re-visit the Firefox navigation bar keyboard combo cheat sheet for some of the other operating systems out there.  Here are all the keyboard shortcuts for the standard navigation bar for the various Linux distros out there.  Hopefully all the most useful ones have made it onto the list, but if there is one I missed, please feel free to add it to the comments.

Ever have a Firefox add-on that just did not want to leave your PC?  Most of the extensions to Firefox are really easy to remove, however sometimes you run into a situation where one is so bad or tricky, it just doesn’t want to let go.  Here are some of the common ways to remove an add-on from Firefox.
The Traditional Way
The way you usually uninstall add-ons from Firefox is to go to Tools and then Add-ons from the menu bar.  [...]

How do you get Firefox’s live bookmarks to refresh faster?  By default, the Live Bookmarks are set to refresh every 60 minutes to check for new headlines.  However, if you want to get your news a little quicker, there is a tweak you can do to make the process go a little faster.
In the address bar, type in about:config, and then hit enter.
At the warning, click the button that says, “I’ll be careful, I promise!”.  Now you are ready to [...]

Worried somebody is going to snoop around on what you are doing from within Firefox?  Have no fear!  Although private browsing hasn’t made its way to Firefox yet, you can still clear your private data in Firefox very easily.
What is Firefox Saving About Me?

Now the first question you may have is what type of content is saved by Firefox?

Browsing History: contains a log web locations you have previously visited.

Firefox works fine, but then the worst might happen (even to you!).  Something goes wonky and Firefox goes from a browsing tool to an annoyance.  So how exactly do you troubleshoot an issue with Firefox?
For most people, I would suggest trying to run Firefox in Safe Mode first.  You can use the command line:  firefox -safe-mode to get there (for Windows users).
On Linux, you can go to your Terminal and run (for Firefox): /path/to/firefox/firefox -safe-mode
On Mac OS X, go [...]

After suggesting a few alternative download links the other day for Firefox themes, I had a few people e-mail me and asking, “How do I install these themes on DeviantArt?”.
Well, with DeviantArt and other places where you download a zip there is an easy (yet a little longer) install process.
For an example, lets say we just downloaded Castripe-iga 2.2 for Firefox. Now you have a zipped up file sitting on your desktop and you don’t know what to do [...]

With the release of Firefox 2, the browser has done a much better job with handling RSS feeds.
Instead of throwing you up a bunch of random XML code they actually give you a pretty nice interface to learn from and use when clicking on that little orange subscription button you see on all the Web sites these days.
For an example, let’s use the RSS feed for Firefox Facts:
http://feeds.feedburner.com/firefoxfacts
Now when you launch that in Firefox, you will be given a clean [...]

TwisterMc is already one of my favorite Firefox theme designers. All of his work always seems to have it’s own individual characteristics and quirks that make it unique as well. So when it comes to learning how to make your own Firefox theme, why not learn from one of the best?
iPox Remix hopes to be a new starting point for people who want to design their own theme, but don’t know where to get started at first. [...]
