Can't run Firefox on Ubuntu 23.10

  • 772

On Terminal, when I try to run Firefox, I get this message:

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

snap install firefox

But it is already installed:

[sudo] password for begueradj: 
snap "firefox" is already installed, see 'snap help refresh'

More information:

begueradj@p50:~$ apt list --installed firefox -a
Listing... Done

Edit:

How to solve this ?

    The previous commentators were right. As I needed to restore my Firefox snap session, I did this:

    snap info firefox

    Output:

    It says that Firefox was disabled. So I enabled it with:

    snap enable firefox

    After I typed my password, I was able to launch Firefox through Terminal: firefox
