Firefox Portable

Mozilla Firefox, Portable Edition (formerly known as Portable Firefox and commonly known as Firefox Portable) is a repackaged version of Mozilla Firefox created by John T. Haller. The application allows Firefox to be run from a USB flash drive, CD-ROM, or other portable device on any Windows computer or Linux/Unix computer running Wine. The program does not require Firefox to be installed on the computer, nor does it leave personal information on the computer or interfere with any installed versions of Firefox, however, installation on the computer's data storage device is possible. The program is not totally portable; it cannot run multiple instances of Firefox out of the box. It is compatible with Windows 7, Windows 8, Windows 10, Windows 11 as well as Wine on Unix-like systems. Although recent versions have serious compatibility issues with WinPE XP and BartPE XP, the old version 2.0.0.20 is compatible with Windows 98, Me, and PE XP and 2000.
