Firefox Snap won't Start under Ubuntu 21.10

I gave it a try and things didn’t go so well. Basically after 25 minutes I gave up. Here is what I did just so we are all in sync. First a shutdown and reboot. Firefox deb is still installed. Here are the snaps installed at the start of this;

Checking to see if firefox is running:

paul@p6t:~$ ps -ef | grep firefox
paul        8822    7007  0 21:11 pts/1    00:00:00 grep --color=auto firefox

verifying that the firefox snap isn’t installed

paul@p6t:~$ snap run firefox -version
error: cannot find current revision for snap firefox: readlink /snap/firefox/current: no such file or directory

Installing the firefox snap

paul@p6t:~$ snap install firefox firefox 93.0-1 from Mozilla✓ installed

Trying to verify the firefox snap version

> paul@p6t:~$ snap run firefox -version
> Importing existing firefox profiles from /home/paul/.mozilla/firefox

After 25 minutes I checked in on HTOP to see if it was still running;

I closed the terminal and opened a new one

paul@p6t:~$ snap run firefox -version
Mozilla Firefox 93.0

Looks promising;

paul@p6t:~$ snap run firefox
