Rein, which in German means “pure”, is one of the best looking simple themes I have seen in a while.  Usually the more colorful themes catch my eye the most but this one is well worth checking into.
Here is a screenshot of this awesome monochrome flavored theme:

You could definitely say this theme was offbeat and a ‘bit different for sure.  You can pick up the Rein theme for Firefox 3 and up over at the Firefox Add-ons web site.  [...]

Need a few more options for your Firefox tabs?  Twanno’s Tab Clicking Options extension for Firefox should do the trick.  With the Tab Clicking Options extension it is possible to set various actions to different clicking events on the tab bar or a tab in the Firefox browser.
The events you can assign an action to are:

Double clicking
Clicking with middle mouse button
Left clicking with control-key (or meta-key on Mac) pressed
Left clicking with alt-key pressed
Left clicking with shift-key pressed
And the actions [...]

The Vixpa theme for Firefox is an attempt to refresh the Windows XP-style icons with the more polished Windows Vista feeling.  Your not getting the same old icons though.  All icons have been redrawn from the ground up, with a few original icons to replace those of XP’s. 
Here you have Vixpa with the normal sized icons:

Here you have Vixpa with the small sized icons:

Well worth checking out if you are missing that old Windows XP look and feel.  [...]

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 [...]

Want to make tagging your bookmarks as easy as clicking an icon?  Tagmarks, the add-on for Firefox, hopes to do just that.  The idea here is to bring one-click bookmarking in Firefox together with the tagging power of the browser.
With Tagmarks, you have a lot of different icons that popup whenever you hover over the traditional bookmarking star you see in the Firefox 3 address bar.  When you click in each icon, it will add the page to the [...]

Want to take Firefox to the Mushroom Kingdom?  This new Mario Bros theme looks fantastic from head to Toad.  Can you tell I am a little excited?

Another nice feature is that if your are using small icons on your navigation bar, your icons get turned into 16-bit versions of the larger ones:

This is not the first Mario-based theme for Firefox.  Do you remember that Super Mario 3 inspired theme?  It did not last long on Mozilla’s site.
With Mozilla’s history with [...]

I have had several requests in the past from people wanting to know if I knew of an extension that would help you add sound effects to tasks in Firefox.
I never did spend too much time on this request because personally I like my browser to be nice and silent.  People with special needs though could use an add-on like this so my search started.  Looking high and low, I found one add-on that promises to do the job, the [...]

It has been a long time since I spend a lot of quality time with Digg.com, but I know a lot of you might be excited to see they released a new toolbar for Firefox 3.  You can divide things into two major features, the new notifications and the toolbar itself.

Here are Digg’s official descriptions of these two new key features:

Time for another TwisterMC original that has gotten updated for Firefox 3. 
This time around it is Mint.  Mint is a flat, small, green and gray Firefox theme.  It is very simple, but does a good job a looking different from the rest of the Firefox theme pack. 

If you like the taste, go pick it up on the Firefox Add-ons web site, and be sure to give TwisterMC your thanks too! 

Well, it is defined by Mozilla Labs as, “An Experiment with Messaging in the Browser”.  They launched this new side project yesterday, and I do have to say – like most things they do – Snowl looks very interesting.
Think of it as mixing the web browsing of Firefox with an instant messenger.  This way you always have your close connections at your fingertips while your out on the Web.  The future roadmap for Snowl looks to deliver:

support for additional [...]
