I have Firefox installed in /opt/firefox as recommended by Mozilla, but it is not recognized automatically by the script:
The FixFx script tweaks Firefox. Make sure Firefox is up-to-date and closed.
Enabled tweaks: 'secondsSeekedByKeyboard=5' 'preventClickSelectsAll'.
Error: No valid Firefox paths found.
Terminating.
