Mozzilla is a free and best browser. Good for user and developer.

Only one review of Mozilla.com? Maybe it goes without saying but in any case, this is the home site of the Firefox web browser and Thunderbird email client. The latter doesn't get that much attention these days, as many web users are moving toward online email accounts, but nevertheless it's a solid competitor for Microsoft offerings if you use POP3 email on your home computer.

As for Firefox, it's currently the most popular of the non-Microsoft offerings, largely due to the endless range of free third-party extensions which allow you to build pretty much any kind of browsing experience. Professionals like it as they can customize it for work, and the rest of us can easily add ad-blockers, flash downloaders, download managers, custom scripts, etc etc etc.

This is not a review of third-party extensions, that wouldn't be possible given the wide selection available, but I'll mention a few that I use myself and recommend.

Adblock plus - say bye bye to almost every ad, everywhere.

Autopager - turns many multiple paged sites (think Google) into one long page, no need to keep clicking "next".

W. O. T - Web Of Trust - be alerted to dangerous sites, recommended to especially useful ones.

TooManyTabs - endless rows of extra tabs for those sites you wish you could fit on the standard bookmark bar, and none of them use any memory until you load the page.

And lastly Greasemonkey, which in itself does nothing but provide a facility to run user scripts in the browser. These scripts mainly alter the look and/or functionality of web pages. Most useful for me: being able to have auto-signing in on Yahoo, which otherwise prompts me for my login every time. And there are many scripts which modify and improve on the experience of using Google pages, too.

There are hundreds of ready-made scripts and hundreds (if not thousands - yet) of tried and tested extensions. But even without a single one of these, Firefox unmodified remains the best alternative browser around. It's fast, reliable and constantly evolving, and it draws little criticism even from die-hard Internet Explorer users.

Even if you love IE8, you can still run as many web browsers as you like on the same machine. Given the widespread appreciation and support that Firefox enjoys, it makes sense to install it and at least play around with it for a while - even if for some reason you still prefer to stick with IE or boldly go with Chrome.
