Firefox, alternative Linux à Opera

Notre avis

Firefox is a solid replacement for Opera for users who value speed, privacy, and extension support. It covers most everyday browsing tasks and offers a customizable interface, but it lacks Opera’s built‑in VPN and ad blocker. If you rely on those features, you’ll need a separate VPN and ad‑blocking extension. For users who prioritize open source and cross‑platform sync, Firefox is a good fit.

Ouvrir vos fichiers Opera

Opera uses its own profile format; Firefox cannot directly read Opera bookmarks or history. You can export Opera bookmarks to HTML and import them into Firefox. For saved passwords, use Opera’s export to CSV and then import via Firefox’s password manager. No direct migration of extensions or settings is possible.

Passer de Opera à Firefox, étape par étape

  1. Export Opera bookmarks to HTML via Settings > Privacy & Security > Bookmarks > Export Bookmarks to HTML.
  2. Export Opera passwords to CSV using the Password Manager and save the file securely.
  3. Install Firefox from your distro’s package manager or Flathub.
  4. Open Firefox, go to Bookmarks > Show All Bookmarks > Import & Backup > Import Bookmarks from HTML to load bookmarks.
  5. Open Firefox’s Logins & Passwords, choose Import from CSV to load passwords.
  6. Adjust Firefox privacy settings to match your preferences, and install desired add‑ons.
