Surf the internet with one of the best alternative browsers available, for both Mac and Windows.
I remember the big Microsoft Antitrust Trial and shake up back in the 1990's. Everyone got their undies in a bunch because it was thought Microsoft making and integrating their own internet browser into Windows created problems for other browser vendors, some of whom tried to sell their browser rather than give it away. Thankfully, we're well beyond all that, and end user choices – good ones – remain available. This is one of the reasons why I really like Mozilla Firefox, and it's available for both Mac and Windows.

Mozilla Firefox is an advanced web browser, based on the Mozilla Open Source project. It's got multiplatform support and a great many features that make it a great choice for the default browser on a computer near you. Chief among those is its advanced, efficient interface.

With Firefox, you can get to your sites quickly, even if you can't remember the URL's. Its Awesome Bar allows you to type a search term within it, and the autocomplete function will include possible matches from your browsing history, bookmarked sites and open tabs. Its adaptive technology learns your browsing habits over time, and will continue to offer better fitting matches the more that you use it.

Above the Awesome Bar, Firefox supports tabbed browsing; making it easier to focus on the content of the sites you visit. You can browse multiple sites at once, simply and easily. Each site appears as a new tab within the current browser window and can be accessed in one click. If you use browser based apps, like Gmail or MS Office 365, you can take these sites off the tab bar and give them a permanent home in your browser.

There is a great deal of information on the internet and Firefox makes it easy for you to find what you're looking for. Its Integrated Web Search makes searching for information easy. The search box, located just to the right of your location bar allows you to select the service of your choice and enter your search terms into the box. The box width is even adjustable if you need more space. As soon as you start typing in the search bar, it will prompt you with a drop down of filled-in suggestions. You can also use the search bar as a calculator, converter and more.

Pros: Free, Fast, Easy to use, Tabbed browsing.

Cons: Rapid update cycle not always seen as helpful.

Conclusion: Mozilla Firefox is one of the best alternative browsers available on the web today. It's easy to use, light, and offers a number of enhancements that you might not find in its competitors. Its update services constantly check for new versions, insuring that updates come to you as soon as they are available. If you're looking for something to replace the default browser for your OS, Mozilla's Firefox is a good, solid choice.

System Requirements

Before installing, make sure your computer meets the system requirements.

Downloading

Mozilla provides Firefox 3.6 for Windows, Linux, and Mac OS X in a variety of languages. You can get the latest version of Firefox 3.6 here. For builds for other systems and languages not provided by Mozilla, see the Contributed Builds section at the end of this document.

Installing

Please note that installing Firefox 3.6 will overwrite your existing installation of Firefox. You won’t lose any of your bookmarks or browsing history, but some of your extensions and other add-ons might not work until updates for them are made available. You can reinstall an older version later if you wish to downgrade.

Uninstalling

You can remove Firefox 3.6 through the Control Panel in the Start Menu on Windows, by removing the Firefox application on OS X, or by removing the firefox folder on Linux.

By default, removing Firefox 3.6 won’t remove your bookmarks, web browsing history, extensions or other add-ons. This data is stored in your profile folder, which can be found by going to the Help menu and selecting Troubleshooting Information.... The button next to the Profile Directory line in Application Basics will open your profile directory in your system's file explorer.

Mozilla Firefox 2.0 Download

Please note that if you keep your profile, any version of Firefox that you install after removing Firefox 3.6 will continue to use the bookmarks, web browsing history, add-ons, and other data from this profile folder.

Extensions and Themes

Extensions installed under Firefox 3.5 may be incompatible and/or require updates to work with Firefox 3.6. Please report any issues to the maintainer of the extension. When you install Firefox 3.6 all of your Extensions and Themes will be disabled until Firefox 3.6 determines that either a) they are compatible with the Firefox 3.5 release or b) there are newer versions available that are compatible.

Known Issues

This list covers some of the known problems with Firefox 3.6, which will be resolved in future releases:

• If FIPS mode is enabled and certain files have been removed from the system, the browser may crash on startup (see bug 522041)

• Content over certain Flash videos may not disappear when the video plays (see bug 571313)
• Older Flash videos on Download.com may fail to play. CNet has been notified of the issue (see bug 569104)
• Some slower machines may see degraded mouse responsiveness when viewing certain Flash videos (see bug 561818)

• Firefox may have difficulty playing system sounds in some distributions of Linux (see bug 536996)
• Zooming out on some sites may result in grey or black lines appearing (see bug 468496)

Troubleshooting

• Poorly designed or incompatible extensions can cause problems with your browser, including make it crash, slow down page display, etc. If you encounter strange problems relating to parts of the browser no longer working, the browser not starting, windows with strange or distorted appearance, degraded performance, etc, you may be suffering from Extension or Theme trouble. Restart the browser in Safe Mode. On Windows, start using the 'Safe Mode' shortcut created in your Start menu or by running firefox.exe -safe-mode. On Linux, start with ./firefox -safe-mode and on Mac OS X, run:

  cd /Applications/Firefox.app/Contents/MacOS/
./firefox-bin -safe-mode

  When started in Safe Mode all extensions are disabled and the Default theme is used. Disable the Extension/Theme that is causing trouble and then start normally.
• If you uninstall an extension that is installed with your user profile (i.e. you installed it from a Web page) and then wish to install it for all user profiles using the -install-global-extension command line flag, you must restart the browser once to cleanse the profile extensions datasource of traces of that extension before installing with the switch. If you do not do this you may end up with a jammed entry in the Extensions list and will be unable to install the extension globally.
• If you encounter strange problems relating to bookmarks, downloads, window placement, toolbars, history, or other settings, it is recommended that you try creating a new profile and attempting to reproduce the problem before filing bugs. Create a new profile by running Firefox with the -P command line argument, choose the 'Manage Profiles' button and then choose 'Create Profile...'. Migrate your settings files (Bookmarks, Saved Passwords, etc) over one by one, checking each time to see if the problems resurface. If you do find a particular profile data file is causing a problem, file a bug and attach the file.
