That's because you haven't installed the real firefox, but only the Debian ESR version. (BTW it won't be in /usr/.) If you were to install it, then the little script that runs when you type "firefox" would divert you to the real one. Just type cat /usr/bin/firefox . What you've missed in the past should still be in here: $ grep firefox.real /var/log/apt/term.log Leaving 'diversion of /usr/bin/firefox to /usr/bin/firefox.real by firefox-esr' $ zgrep firefox.real /var/log/apt/term.log* | wc -l 64 $ Cheers, David.
