Falkon as a Linux alternative to Firefox
Updated
Our verdict
Falkon is a functional, lightweight alternative for basic browsing but lacks the depth of Firefox. It suits users who prioritize low memory usage and simplicity over a vast extension ecosystem or complex profile syncing. You lose hardware-accelerated video performance and cross-platform profile synchronization. If you rely heavily on specific Firefox add-ons or need consistent behavior across Windows and Linux, stick with Firefox. Falkon works well if you just need a fast, native Linux browser with built-in ad blocking and standard tab management.

Opening your Firefox files
Falkon can import bookmarks and passwords from Firefox using standard browser import tools or manual JSON/CSV export. However, it does not natively read Firefox's internal profile database format directly. You must export data from Firefox first. Extension compatibility is not guaranteed, as Falkon uses a different plugin architecture than Firefox.
Switching from Firefox to Falkon, step by step
- Export bookmarks and passwords from Firefox to HTML or CSV.
- Install Falkon via your package manager or Flathub.
- Import the exported bookmark file into Falkon.
- Manually re-enter any critical saved credentials if import fails.
- Install essential Falkon plugins for ad blocking if not enabled by default.
- Test hardware-accelerated video playback on your specific hardware.
