I had problems with Jerboa too. First it won't login, so i used to just browse without logging in. Then from today it just closes on starting. Got fed up and uninstalled it. Thunder works but keeps showing some blank page with error every minute. Tried wef or something which is a browser app but didn't like it. So ended up using Chrome but it uses too much battery so ditched that for Firefox now. I wonder if there is some rss feed for lemmy.
