Tabbed browsing lets you keep several pages open in one Firefox window, while integrated search puts web searches within reach from the browser. Mozilla Firefox Portable packages the browser for use from removable, local, or cloud storage, with bookmarks and extensions available as you move between computers.
Firefox Portable carries bookmarks and extensions
The portable edition keeps a browser workspace with the app, so bookmarks and installed extensions can go along on its storage device. Open the same portable copy on another computer to continue with that setup. The portable launcher is designed to keep personal information from being left on the computer where the browser runs.
Firefox retains its familiar browsing tools: tabs, integrated search, popup blocking, and privacy features. A private window is available for browsing that should not be added to the regular browsing history.
Run the browser from removable or local storage
Firefox Portable runs without a conventional installation on the host computer. It can be launched from a USB drive or other removable storage, as well as from local or cloud storage. This arrangement suits people who use different Windows computers and want to keep browser preferences and add-ons together.
- Keep the portable browser files on the drive or storage location you plan to carry.
- Launch Firefox Portable from that location when you want to use its saved browser workspace.
- Use Firefox tabs and search as you would in the standard browser.
Moving the portable copy can affect some settings
A path containing non-ASCII characters can affect portability if the app is later moved to a different location. Some settings or extensions may not transfer fully in that case. Keeping the portable files together at a consistent location avoids that specific path-related issue.
