This inspirational theme, created for the Firefox browser, is one of the most attractive themes I have seen in some time.  Designed with the idea in mind that simple/flat designs tend to be more appealing than overly decorated ones; Purity is ready to refresh your browsing experience.
The author of the theme notes that some of the theme is still a work in progress, as many of the dialog icons are from the stock Aero theme.  However I have [...]

Does it seem that Firefox 3.5 is a little sluggish when it starts on your Windows-powered machine?
Due to some unknown reason, Firefox on Windows pulls certain file locations for security reasons.  In turn, having too many temporary, history or recent document files will slow down Firefox 3.5’s data generation process.  A bug has been filed about this, but in the mean time – the best thing you can do to help fix it is to do a little house [...]

Split Browser, the add-on for Firefox, splits up the content area of the browser in as many windows as you like.  Each window you see, also has its own mini browser inside.

This is a really helpful extension for those people out there that work on multiple pages at the same time and down want to have two Firefox windows open side by side or don’t want to switch between tabs.  There are several ways you can decide to split [...]

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.  [...]

Thanks to Percy over at Mozilla Links, we now have a Firefox 3 Vista preview worth gawking at (theme-wise anyways):

My first thoughts were “oh, it’s shinny and blue” but it does the job it sets out to do. It does fit into the Windows Vista look and feel pretty well, don’t you think?

Hey, here is a cool new tip I just found out about. Say you have two Firefox Windows open with both having multiple tabs. You can drag a tab from one Firefox browser window to the next. Here is a better description of the cool tab tip from the source:
Users who have tabs open in multiple Firefox windows can drag and drop tabs across separate browser windows. Using this technique you can consolidate all of your tabs [...]

Which one gives you a better performance? Is it better to have multiple tabs open in one window or just have multiple Windows open? The Firefox Guru did all of the scientific work on this one, and has found out the results for us.
Over on Go Firefox!, an interesting question was posted: Which uses less system resources (memory)?
My theory is using tabs would use less resources then having the same sites opened in separate windows. My reasoning is [...]

Now I don’t really mind Thurrott because I don’t know him or his writing very well.
It sounds like to me though he is just trying to get attention by being anti-Firefox when the rest of the world is swinging in the other direction. As Asa points out he has it all wrong on some of Firefox 2’s new features.
Paul Thurrott, in his somewhat late review, takes a look at Firefox 2’s new features. Unfortunately, and something I [...]

I just hate it when a Web site tries to resize my browser window.
There’s a simple little fix that prevent webpages from resizing your Firefox browser that I put in every time. There’s nothing I hate more than a website that resizes my whole browser to the size of a 40×40 ad, forcing me to expand it back to my regular 1024×768 size.
