Mozilla Firefox, alternative Linux à Google Chrome

Mis à jour le 18 octobre 2026

Notre avis

Mozilla Firefox is a solid replacement for Google Chrome on Linux. It offers comparable speed, strong privacy defaults, and a mature extension ecosystem, making it suitable for everyday browsing, web development, and privacy‑conscious users. Power users who rely heavily on Chrome‑specific features like built‑in PDF viewer quirks or certain Chrome‑only extensions may need to adjust, but for most tasks Firefox works just as well.

Ce qui change

Firefox uses the Gecko engine instead of Blink, affecting some site rendering quirks
Built‑in tracking protection and stricter privacy defaults out of the box

Ouvrir vos fichiers Google Chrome

Firefox can open any standard web page, bookmark file (HTML), or password export that Chrome produces. Importing Chrome bookmarks is straightforward via the browser’s import wizard. Exporting Firefox data to Chrome isn’t automated, but you can export bookmarks as HTML and import them into Chrome manually. Other proprietary Chrome data formats (e.g., Chrome’s sync data) have no direct equivalent, so manual migration is required.

Passer de Google Chrome à Mozilla Firefox, étape par étape

Install Firefox from your distribution’s package manager.
Launch Firefox and run the built‑in import wizard to pull Chrome bookmarks, history, and saved passwords.
Export Chrome bookmarks as an HTML file (chrome://bookmarks) and import them into Firefox if the wizard missed any.
Reinstall needed extensions from Firefox’s add‑on site.
Set Firefox as the default browser in your desktop environment.
Adjust privacy and UI settings to match your preferences.
