Mozilla Firefox Portable

Firefox Portable lets you carry your complete browser setup on a USB drive, memory stick, or external hard drive. Run it on any Windows computer without installation — your bookmarks, extensions, passwords, and settings travel with you.

This version is built for people who move between multiple computers or don't have a fixed workspace. Plug your portable device into any Windows PC, launch the browser, and pick up exactly where you left off. All your browsing data stays on your device, never left behind on a host computer.

Firefox Portable works independently of any standard Firefox installation already on the machine. No setup required — just execute it directly from your storage device. Your profile and all customizations are saved in the portable folder, so every change you make carries over to your next session on a different computer.

Ideal for users who need a consistent, private browsing environment across different workstations, or who want to keep their data fully under their control. Take your web browser anywhere without relying on cloud sync or leaving traces on shared computers.

Download Mozilla Firefox Portable to run a fully configured browser from any removable storage device.
