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.

Any rolling release still wins because they are at version 2024.1.9
