Mozilla Firefox is a free, open source, cross-platform, graphical web browser developed by the Mozilla Corporation and hundreds of volunteers. Beginning as a fork of the browser component (Navigator) of the Mozilla Application Suite, Firefox has since become the Mozilla Foundation's main development focus (along with the Thunderbird mail and news client), replacing the Mozilla Suite as the foundation's official main software release. The current version is 3.5, released on June 30th, 2009. The first version of Firefox was released November 9th, 2004 as version 1.6; before that the browser was known as Firebird, and before that, Phoenix.

Pros
- Extensive functional add-ons (extensions) and plug-ins
- Tabbed browsing
- After a crash can "Restore session" which reopens all tabs
- Open-source project
- Fewer security exploits directed at Firefox vs. IE
- Page loading can be significantly faster than IE, especially when using speed-enhancing plugins.
- In page searching and highlighting is powerful and straightforward. Just slash and type, or F3 refind: easy!
- Faster browsing in v3
- "Awesome bar" learns and adapts according to the frequency and recency of pages you visit
- Improved memory usage in v3
- Built in error console for debugging Javascript and CSS
- Site Icons for easier recognizing of web pages
- High standard-compliance
- Built in hierarchical Bookmarks Toolbar. Easier usable than scrolling through a sidebar. (just point and click not click - expand - click - expand - click)
- Great for web developers: design and debugging.
- New Complete Page Zoom in V3 with resampled pictures - really useful and way better than IE 7 Zoom.
- DOM browser can be used to learn about web pages and customize the browser itself.
- Its easier to integrate into different OS themes (e.g. using Windowblinds).
- Speed - reloading 5 tabs on browser startup takes 4 seconds (FX 3.0.5), the same task with Internet Explorer 7 takes 14 seconds (until all tabs are fully loaded). This is on a Athlon 64 6000 with 2 Gbyte Ram under Windows XP Pro.
Cons
- Websites designed with proprietary IE/Active X code may not render correctly
- Firefox V2 crashes semi-regularly and uses a lot of computing resources
