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

   snap install firefox

   snap "firefox" is already installed, see 'snap help refresh'

Hi all. I have been using firefox with ubuntu 22.04 for about since when ubuntu 22.04 was released (2022). On firefox, I usually use the nordpass and tab grouping extensions. For the third or fourth time in a row, firefox has simply vanished from my system from day to night. I click the icon and nothing happens. I try typing "firefox" in the terminal and get Command '/usr/bin/firefox' requires the firefox snap to be installed. Please install it with: snap install firefox Even if I accept the bizarreness of snap simply deciding from one day to another that I don't have this package (or did I never have it and never needed it in the first place?) and try "snap install firefox" I get: snap "firefox" is already installed, see 'snap help refresh' After reading the result of "snap refresh help" I decided to "snap refresh" to update all of it's packages. Still, "snap install firefox" and "firefox" keep giving me the same result. What is happening here?
