About Firefox

Mozilla Firefox is a free, open source, cross-platform, graphical web browser developed by the Mozilla Corporation and hundreds of volunteers. The browser began as a fork of the Navigator component of the Mozilla Application Suite; Firefox has since become the foundation's main development focus (along with its Thunderbird mail and news client), and has replaced the Mozilla Suite as their official main software release.
Firefox includes tabbed browsing, a spell checker, incremental find, live bookmarking, a download manager, and an integrated search system that uses the user's desired search engine. Functions can be added through add-ons created by third-party developers, the most popular of which include the NoScript JavaScript disabling utility, Tab Mix Plus customizer, FoxyTunes media player control toolbar, Adblock Plus ad blocking utility, StumbleUpon (website discovery), Foxmarks Bookmark Synchronizer (bookmark synchronizer), DownThemAll! download enhancer, and Web Developer toolbar.

Firefox Features:

  • Remember site passwords without ever seeing a pop-up.
  • Bookmark, search and organize Web sites quickly and easily.
  • View Web pages faster, using less of your computer's memory.
  • Find the sites you love in seconds - enter a term for instant matches that make sense.
  • Avoid online scams, unsafe transactions and forgeries with simple site identity.
  • See any part of a Web page, up close and readable, in seconds.
  • Browse with a Firefox that's integrated into your computer's operating system.
