Installing Firefox

Basic installation instructions can also be found in the Firefox release notes.

All Systems

Firefox system requirements are listed [here]. Download the latest version of the Firefox installer for your system from mozilla.org. If you install Firefox on a multi-user system where access privileges are restricted, you must run Firefox as a user with access to that location upon installation so that all initial startup files are generated.

Note: In most cases, you can install a newer version of Firefox over an existing 1.0 or later version [1]. If you prefer a clean install, Uninstall your current Firefox version and delete the installation directory before launching the Firefox installer.

Windows

Download the Firefox setup .exe file to your desktop. After the download has completed, close the browser and any other running programs.

• Optional: Open the Windows Temp folder (Windows 98/ME: Start -> Run -> Type C:\Windows\Temp -> OK. Windows 2000/XP: Start -> Run -> Type %temp% -> OK). Select all files and folders and delete, then close the Temp folder window.

Double-click the downloaded Firefox setup .exe file to launch the installer.

Mac OS X

After downloading the Firefox .dmg file, double click the Firefox Disk Image to open it in Finder, and then drag the Firefox application onto your hard disk. Be sure to drag the Firefox application out of the disk image and onto your Hard Disk before running it. Do not double click the icon in the disk image!

Linux

Download the Firefox .tar.gz file. When download is complete, use an archiving utility such as Ark to extract the Firefox files. When extraction is complete, execute Firefox.
