Firefox won't run on Ubuntu 22.04

When I click on the Firefox icon it seems to work because the little wheel appears and revolves. However, it soon disappears then nothing else happens. When I go into the terminal and ask which firefox the result is /snap/bin/firefox but when I use this path in terminal it doesn't work. I cannot find firefox in anything called 'bin' it is in the snap folder.

I'm having the same problem. Here is 'snap list --all' and results of running firefox on the command line. Note: when launching from the command line, firefox runs in spite of the warnings. (Adding the info here since I'm unable to comment.)

~$ snap list --all
