I tried to uninstall and reinstall firefox thinking it would fix some bug I had with my microsoft 365 login. Now eventhough firefox seems to be propely installed, I can't open it with the icon, neither through the command line.

I followed the instructions from this post : Removing Firefox in Ubuntu with all add-ons like it never existed (main steps involved sudo apt-get purge firefox and rm -r .mozilla/firefox/ (I got sacred to further delete protected files in /usr/ or /etc/ )

I reinstalled using sudo apt-get install firefox but I get :

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
firefox is already the newest version (1:1snap1-0ubuntu2).
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

When I type firefox I get :

Command '/usr/bin/firefox' requires the firefox snap to be installed.
Please install it with:

snap install firefox

But when I snap install firefox I get snap "firefox" is already installed, see 'snap help refresh'

I tried to restart my computer but I always get stuck. I see the firefox icon on the desktop but it doesn't launch.

Additional informations :

-Output of echo $PATH :

/usr/local/MATLAB/R2023b/bin:/home/dsutterlin/.local/bin:/home/dsutterlin/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin
  • There is a an executable file in /usr/bin/firefox
  • I created a ./mozilla/ file in my /home/ but it's empty
  • Ubuntu version : 22.04.4

Thanks for the help!

It seems to me that you have the snap version of firefox installed but you tried uninstalling it with apt, both apt and snap are different package managers.

First try

type firefox

if you get an output similar to

firefox is hashed (/snap/bin/firefox)

it means you have the snap version installed in which case you should use

snap remove firefox

after that run

sudo apt-get purge firefox

to remove any remaining information and then finally to re install try

sudo apt-get install firefox

that should solve the issue
