I use Firefox, almost exclusively, for all of my internet needs. I like the rendering, the plug-ins, and the way it looks. I think, for work at least, the reason I like Firefox the most is the ability to set a proxy server independent from the Windows proxy settings.

This is different from any other browser I've tried, with the exception of K-Meleon ... which is based on an older version of Mozilla's browser. Have a look at the following browsers proxy configuration setup boxes:

Safari

Chrome

Internet Explorer

As you can see, they all use the Windows Connection settings, so if I change my proxy settings in Safari, they also change in Chrome, Internet Explorer, and Windows (Vista desktop widgets, Twitter clients, Windows Live Messenger, miscellaneous other software). This is the main factor keeping me from switching to Google's Chrome browser.

At work, I have tools that work best when connected to US proxies and others that work best when connected to American proxies. Therefore, I cannot use Chrome and Internet Explorer at the same time on different proxies because they both use the same proxy server settings ... and IE is required by a lot of my work webtools.

Now, take a look at Firefox:

Firefox

Firefox, and other Mozilla based browsers, have their own proxy server settings ... they are completely independent from Windows. So, I can have two browsers open, each connected to a different proxy server, and access all of the tools I need for work and I want for my entertainment (I have a very boring job).

I do like Firefox, for many reasons, but I would switch to Chrome (or at least give it very serious consideration) if I could set it to a proxy server independent of Windows.

My home computers are a completely different story ... just waiting on Google to go Open Source (as advertised) and create a Linux version of Chrome.
