@apub I am having the same problem as you. I have a Mac mini with Catalinia 10.15.7. Safari and Firefox both seize up. Firefox actually shuts itself down after a while. Safari is giving me the same message as above. The Brave browser actually will load but none of the overlays do anything. I tried showing radar and satellite and neither of them do anything. I'd say it's a Mac thing, not a browser thing.
