I think there’s still something wrong with your setup… You should be able to have as many Firefox windows and tabs as you’d like without using too much RAM, since they should de “suspended”.
I regularly have hundreds of tabs running fine, on 32GB of RAM.
Most likely it’s a vscode extension that’s leaking memory, and this problem will still happen after your upgrade, just take longer.
Q: what does
apt install firefox
do? Surely it uses apt to install Firefox, right??? A: The command gets highjacked by snap, which promptly crashed and hangs.Ran into this just a few hours ago, made the mistake of suggesting Ubuntu as a sane default (instead of debian or something else), never making that mistake again hopefully.
