The last Ubuntu update (a couple of days ago) basically turned Brave ad Chrome into toast. This bug: https://bugs.launchpad.net/ubuntu/ source/chromium-browser/ bug/2020604 was responsible apparently (at least on Chromium based browsers). Firefox was left unborked by this bug. So, for a couple of days while this emergency triage was being implemented I went back to Fx. A browser that I'd forgotten was so good. As of today, June 1st, Chrome and Brave are back now, Chrome was unborked yesterday. I had Brave as default for a while. After this fandango I'm keeping Firefox as default.
Speaking of borking, the latest 5.19.0.43 kernel broke VM in Kubuntu, resulting in a black screen! Had to downgrade to 5.19.0.32 to get a functional desktop back. Then I put it on the LTS 6.1.32 kernel. No issues!
