Something completely ruined Opera. Every version after 66 is plagued by freezes and "Not responding" pages. I'm tired of fighting this, Opera has become unusable. I've managed to freeze my Opera at v.66 but it obviously can't be a permanent fix. Initially, I was hoping these problems were just "growing pains" but new versions come and go and it doesn't get better. I can't be the only one with these problems, so any ideas?
