Hi, IMO the output of htop is confusing, not only because it does use a different colour theme on my machine. I'm also confused by the output of about:memory. I don't know if the output of about:processes is correct or complete, but this output does look human readable to me. FWIW I'm neither using claws-mail, nor KDE, but the memory usage shown by about:processes is less than 0.5 GiB, with an about:processes tab + a Google tab + a dict.cc tab, using a Firefox theme and a few extensions. I suspect that if I would use claws-mail and KDE, the output of Firefox about:processes would be almost or exactly the same. I could recommend another Browser, window manager without a DE and MUA, but this isn't probably much helpful. I would start with --safe-mode, then probably use a complete fresh profile and/or add a new user with a virginal $HOME for testing purpose. I don't want to participate in recommendations, but I make an exception related to a browser wouldn't touch with a barge pole. A pro for Firefox: Brendan Eich left Mozilla A con for Brave: Brendan Eich owns Brave I wouldn't use Brave, even if it would be the best browser available, I even wouldn't use it, if it would be the only browser available.
