Unser Fazit

Firefox on Linux is the same product as the Windows version, so it is an excellent replacement for users who want the same features, performance, and privacy controls on a Linux desktop. It works well for developers, power users, and everyday browsers, providing fast page loading, strong tracking protection, and full add‑on support.

Was anders ist

  • No native Windows‑only extensions that rely on COM or ActiveX

Ihre Mozilla Firefox-Dateien öffnen

Firefox on Linux can open and export bookmarks, passwords, and history from the Windows profile by copying the profile folder (usually located in %APPDATA%\Mozilla\Firefox) to the Linux profile directory (~/.mozilla/firefox). The import/export tools are identical, so no special steps are needed beyond copying the data.

Von Mozilla Firefox zu Firefox wechseln – Schritt für Schritt

  1. 1. Install Firefox from your distribution’s package manager or Flathub.
  2. 2. Launch Firefox once to generate a default profile folder.
  3. 3. Copy the Windows profile folder (e.g., C:\Users\<user>\AppData\Roaming\Mozilla\Firefox) to the Linux profile directory (~/.mozilla/firefox).
  4. 4. Rename the copied profile folder to match the new profile name or set it as default in about:profiles.
  5. 5. Restart Firefox and verify bookmarks, passwords, and extensions are present.

Häufige Fragen

Will my extensions work on Linux?

Most extensions that rely only on web APIs work on Linux. Those that use Windows‑specific APIs (e.g., COM) will not.

Can I sync my data across devices?

Yes, Firefox Sync works the same on Linux, syncing tabs, history, bookmarks, passwords, and settings.

Is Firefox on Linux as fast as on Windows?

Performance is comparable; on many Linux systems it can be faster due to native rendering engines and fewer background services.
