@lemmy.worldI have a laptop with 4GB of RAM and it works fine, my fedora i3 installation. It's nothing compared to a proper computer but it's not like I ever run out of RAM either. (Generally I open two Firefox windows, discord and vscode)
I would say it's about thunar configuration or URL handler configs more than anything. The other comment has what looks like a good solution for x11, no idea if it works on Wayland though.
Cleaning is the only thing that came to my mind. Now I wish I hadn't looked at the comments…
