Curiously, since the last update I have the problem where Safari tabs go completely white after a while. Refreshing doesn‘t help. I have to copy the URL and paste it into a fresh tab.
I’ve had this one for at least a year. Suspended tabs won’t come back 1/4 of the time, and the URL is gone too; the tab is effectively gone. I’m keeping important tabs in Brave.
I just found there's two separate bugs: sometimes the page goes blank but the URL stays, sometimes it loses the URL too and the back/forward button so everything's gone.
