Since the last Catalina update (10.15.4) Firefox is almost unusable for me, whereas it was buttery smooth before. There are constant multi-second freezes and when I switch tabs I often see a gray loading screen before the content shows up a few seconds later. Never saw that happen before. Maybe it's just a coincidence and has nothing to do with the Catalina update, but I am interested whether other people experience the same.

- asdff 6y agoI experience this in a lot of different apps on catalina. just a brief flash of something. Seems to have gone away in 10.15.5, but I've only had the update for an hour.
