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.
Yeah, we tried using Livewire at work, wouldn’t recommend it for any usecase. Very buggy and unfinished, many times you’ll still need to fallback to JS, passing certain data types to Livewire components is just not supported.
