Hi,

No matter how you start firefox, Plank will always link to
/usr/share/applications/firefox.desktop and since
/usr/lib/firefox/firefox is hardcoded there, next time
you start firefox from plank it won't be firejailed.
I tried every trick, but the only thing that works to get
plank to start a firejailed firefox is to directly edit
/usr/share/applications/firefox.desktop and edit out
/usr/lib/firefox everywhere.

Modifying package installed files is not a great idea.

Perhaps plank should behave otherwise. Maybe it can't
because of X limitations or something or it would
involve adding too much code complexity. Anyway
it just won't pick up the
~/.local/share/applications/firefox.desktop file
created by firecfg.

Brave which has Exec=brave in it's .desktop file works
fine with plank and firejail.

My suggestion to fix this problem is to add a
/usr/bin/firefox symlink to /usr/lib/firefox/firefox and then
not hardcode /usr/lib/firefox/firefox directly in the .desktop
file. Then it will just work like Brave and the
/usr/local/bin/firefox symlink to firejail will be started
instead of /usr/lib/firefox/firefox if it is there.

Package versions:

firefox 85.0.2-1
firejail 0.9.64.4-1
plank 0.11.89-2
