I get the messages of Pending update of Firefox snap in my notifications every day despite Firefox being up to date on my machine. Why do I get those notifications and how do I fix them. I use Ubuntu 22.04.
I don't really know since I do not use snap - but you could remove the Firefox Snap package and use the mozilla ppa instead to install Firefox
sudo snap remove firefox
With the Firefox Snap package uninstalled from Ubuntu 22.04 LTS, you’ll need to remove the “firefox.tmp” folder from your “Downloads” directory. You can remove this folder with the following rm command.
From sniffing around and commentary elsewhere, the current Firefox Snap has issues. If this is a new problem, you can probably be patient and it will resolve itself with the next update. If this problem has existed for a while, I'm not sure what to suggest - except maybe following the advice above and using the PPA version - being careful to remove the Snap version along the way.
