i also use arch and firefox/mullvad browser do take a lot longer to launch than normal. my problem could be some dependency missing (ive already got problems with video codecs i have no idea how to fix) or a broken swap partition. So, does reinstalling firefox help? and do you have a swap part? if yes, how big did yoy make it?
Nope, right from the repos.
Ubuntu ships Firefox as a snap now so you have to get it from outside of the repo if you want it to be normal.
I’m on Arch.
Me too, never slow. Is this machine really old?
What’s your DE?
No DE, just Openbox.
There’s a few suggestions about debugging it in Fedora, you should be able to replicate most of them. https://fedoraproject.org/wiki/How_to_debug_Firefox_problems
