I upgraded recently my OS to Ubuntu 22.04.4 LTS. My previous Firefox which was working great under Ubuntu 20.04 stopped launching. I downloaded a new Firefox (Firefox-126.0) and got it install and still same problem. Is Firefox is not supported any more by Ubuntu 22.04.4 LTS? How I can fix this problem and be able to use Firefox again?

These are the steps I followed and found in the link mentioned by Archisman Panigrahi How to install Firefox as a traditional deb package (without snap) in Ubuntu 22.04 or later versions?
To remove the Snap Firefox version ( which is stopping Firefox from launching )
Do the commands starting by the sign ( -> )
-> sudo add-apt-repository ppa:mozillateam/ppa
-> echo ' Package: * Pin: release o=LP-PPA-mozillateam Pin-Priority: 1001
Package: firefox Pin: version 1:1snap* Pin-Priority: -1 ' | sudo tee /etc/apt/preferences.d/mozilla-firefox
-> sudo snap remove firefox
....
If you see the following error below:
error: cannot perform the following tasks:
- Remove data for snap "firefox" (1943) (unlinkat /var/snap/firefox/common/host-hunspell/en_ZA.dic: read-only file system)
..
==>> Then do the following command to Verify that indeed
( /var/snap/firefox/common/host-hunspell ), is mounted as an "ext4" file system using the command below:
-> lsblk -fe7 -o+ro
....
-> sudo systemctl stop var-snap-firefox-common-host\x2dhunspell.mount
-> sudo systemctl disable var-snap-firefox-common-host\x2dhunspell.mount
Then the uninstall command to remove finally the snap version of Firefox:
-> sudo snap remove firefox
Followd by the "APT"'s command below to install Firefox:
-> sudo apt install firefox
....
Note: If in the future Firefox sends a new update and the problem starts again then repeat the whole procedure all over again
