Vivaldi, alternative Linux à Firefox

Mis à jour le 21 octobre 2026

Notre avis

Vivaldi is a solid replacement for Firefox on Linux for users who want deeper control over their browsing experience. It matches Firefox’s core functions—HTML5 rendering, tabbed browsing, extensions, password manager, private mode, hardware‑accelerated video, and sync—while adding advanced tab management, built‑in mail and calendar, notes, and a powerful ad/tracker blocker. Power users who need custom toolbars, keyboard shortcuts, or integrated productivity tools will appreciate Vivaldi more than the stock Firefox experience.

Ouvrir vos fichiers Firefox

Firefox profile data (bookmarks, passwords, extensions, settings) can be exported from the Firefox profile folder (usually ~/.mozilla/firefox) and imported into Vivaldi by copying the relevant files into Vivaldi’s profile directory (~/.config/vivaldi). Vivaldi will detect and migrate most data automatically. For email or calendar data, Vivaldi’s built‑in clients use standard protocols (IMAP/POP3/CalDAV) so you can simply re‑add your accounts.

Passer de Firefox à Vivaldi, étape par étape

1. Back up your Firefox profile folder (~/.mozilla/firefox) and any extensions you want to keep.
2. Install Vivaldi from Flathub or your distribution’s package manager.
3. Run Vivaldi once to generate its profile directory (~/.config/vivaldi).
4. Copy the bookmarks, logins.json, and extensions folder from the Firefox profile into the Vivaldi profile, preserving sub‑folder structure.
5. Restart Vivaldi; it will detect the copied data and import it. If needed, re‑add email accounts in the Mail client.
6. Verify that bookmarks, passwords, and extensions work before uninstalling Firefox.

Questions fréquentes

Does Vivaldi support Firefox extensions?

Vivaldi does not natively run Firefox add‑ons. It supports Chrome extensions from the Chrome Web Store, which covers most popular add‑ons, but some Firefox‑specific extensions will not work.

Will my Firefox bookmarks sync automatically with Vivaldi?

Vivaldi has its own sync service. After importing bookmarks, you must set up a Vivaldi account and enable sync; bookmarks will then sync across devices. Firefox Sync will not sync to Vivaldi.

Is Vivaldi free on Linux?

Yes. Vivaldi is free to download and use on Linux. It is distributed under a proprietary license but does not require payment for any features.
