Hi, I know this topic is covered on the Web but from what I read, it' supposed to be an occasional problem. But it has become a multiple daily time problem for me. I know a reboot does the trick but 2-4 reboots a day. Not sure about that. So does somebody know the real reason for this bug. Is it Catalina, this version of Safari, 15.5, AdBlock 1.2.8 extension? There are no other extensions btw. This has become annoying to the point I'm thinking of using another browser period. Some cues are welcome. Thanks a lot.
