Discovered Firefox's "about:performance" page, confirmed what I already suspected: Mastodon webapp is the worst thing I use. Lightweight alternatives? For real computers, not phones. A good old fashioned desktop app would be best, but I would entertain a locally running webapp, especially if it used technologies more than a year or two old, which I've actually heard of. JS-free would be best, but I scarcely dare to dream. Can't run Brutaldon as no cutting edge Python on Deb stable. Help!
