First randomly jumping Tabs pestilence with that error persisting for many weeks on Opera, and now this. Who reimburses for me the entire deletion of my history with my most important web domains, which history I really needed daily and now with the Opera teams unnecessary dabbling with features that hinder normal, sound use of this otherwise good browser. I'm really depressed with these feature addons that do this sort of damage. I have the right to criticize when these kinds of pestilences continue on and do this kind of harm. Actually I'm quite furious and totally fed up with these. I really needed that history.
