Thank you for your bug report. Is firefox in normal mode working? Using the -safe-mode option works correctly and prompt with a dialog, what does it do exactly for you, just exit with the cmdline errors?

Can you please elaborate on how safe mode doesn't work? Is the application not launching at all? Is its execution malfunctioning?

Hi,

I am using ubuntu-20.04.4 on my desktop PC.
This PC has a Geforce 8600GT and Firefox will not work unless performance setting is turned off.
I tested jammy-desktop-amd64.iso(2022-04-19), it work fine.
but I tested ubuntu-22.04-desktop-amd64.iso( 2022-04-19 ), it is not work.

Hi,

Firefox in snap package does not work,
so I replaced it with deb package.

I think Firfox in deb package work as same as ubuntu-20.04.
