Thank you a lot for the solution.
I wrote also to the improvement desk:
"I’m using Opera since version 3 and even sustained it financially at the begin, buying the new versions. Since version 100, the new Speed Dial is terrible, unreadable and looks like the worst extensions of Chrome or Firefox. Where is our beautiful and original Norvegian design, buddies? It’s like to get vegetal Pølser (hot dogs in Norway) instead of true pork. 
So that I returned to version 99.0.4788.88 (attachement) and blocked autopudate.exe."
