The newest version of our favorite open source web browser, Mozilla Firefox 3, offers dozens of new features and fixes, but only a handful will make the most dramatic difference in your everyday browsing.

A portable application (portable app), sometimes also called standalone, is a program designed to read and write its configuration settings into an accessible folder in the computer, usually in the folder where the portable application can be found. This makes it easier to transfer the program with the user’s preferences and data between different computers. A program that doesn’t have any configuration options can also be a portable application.

Portable applications can be stored on any data storage device, including internal mass storage, a file share, cloud storage or external storage such as USB drives and floppy disks—storing its program files and any configuration information and data on the storage medium alone. If no configuration information is required a portable program can be run from read-only storage such as CD-ROMs and DVD-ROMs. Some applications are available in both installable and portable versions.

Download Firefox Portable

If you were able to load websites until you updated Firefox or until your Internet security software was updated, reconfigured or a new one was added, your Internet security software (including firewalls, antivirus programs, anti-spyware programs, and more) is likely preventing Firefox from connecting to the Internet.

Note: Some Internet security programs can block Internet access even when they are in a 'disabled' state.

In general, you should make sure your Internet security software is up-to-date and remove Firefox from your program's list of trusted or recognized programs, then add it back. For instructions on how to configure some programs, see the Configure firewalls so that Firefox can access the Internet article.

If you connect to the Internet through a proxy server that is having connection problems, you will not be able to load websites. To check your connection settings in Firefox:

    • If you connect to the Internet through a proxy, compare Firefox's settings to another browser's (such as Internet Explorer — see Microsoft's guide to proxy settings)(such as Safari — depending on your OS X version, see Mac OS X 10.6: Enter proxy server settings, OS X Lion: Enter proxy server settings, or OS X Mountain Lion: Enter proxy server settings).

  • If you have an antivirus or Internet security program, update its detections database and do a full scan of your system.
  • If you still have problems, follow the instructions in Troubleshoot Firefox issues caused by malware.
