Mozilla Firefox, alternative Linux à Mozilla Firefox

Mis à jour le 18 octobre 2026

Notre avis

Mozilla Firefox on Linux is a direct replacement for the Windows version. It offers the same rendering engine, extension ecosystem, and sync features, so anyone who relies on Firefox for everyday browsing, development, or privacy will feel at home. Linux users who need a stable, standards‑compliant browser with built‑in tracking protection and cross‑device sync will find it fully adequate.

Ce qui change

Linux package may be delivered via distro repositories or flatpak, affecting update cadence
Integration with Linux desktop environments (e.g., system theme, file dialogs) differs from Windows

Some corporate policies may block automatic profile migration on Linux

Ouvrir vos fichiers Mozilla Firefox

Firefox stores bookmarks, passwords, and settings in a profile directory. The same format is used on Windows and Linux, so you can copy the profile folder (or use the built‑in import/export tools) to move data between the two systems. Exporting to HTML for bookmarks works on both platforms, and passwords can be synced via Firefox Sync if you enable it.

Passer de Mozilla Firefox à Mozilla Firefox, étape par étape

Install Firefox from your distribution's repository or via the official tarball.
Launch Firefox and sign in to your Firefox Account to sync bookmarks, passwords, and settings.
If you prefer a manual move, copy the %APPDATA%\Mozilla\Firefox\Profiles folder from Windows to ~/.mozilla/firefox/ on Linux.
Import any exported HTML bookmark files via Bookmarks → Show All → Import and Backup.
Verify extensions are installed and re‑enable any that were disabled after import.
Adjust privacy and performance settings to match your Windows configuration.

Questions fréquentes

Will my Windows extensions work on Linux?

Yes, extensions that are written in JavaScript and use the WebExtension API work on both platforms. Some legacy XUL extensions are no longer supported.

Can I use Firefox Sync on Linux?

Absolutely. Sign in with your Firefox Account and all synced data (tabs, bookmarks, passwords, history) will appear on the Linux installation.

Is there any performance penalty on Linux?

Firefox runs at comparable speed on Linux. Performance depends more on the desktop environment and graphics drivers than on the OS itself.
