I have successfully switched to another browser. I asked myself
why do I need Opera and
why do I actually need another browser?
So I have switched to the Edge. It is built-in, no need to install something from the 3rd party, I believe it is as safe as Opera or any other modern browser and has the same functionalities.
The final drop of despair was when one field in some web form didn´t work but it was working in every other browser I tried.
No... No... No more, Opera, thanks and bye.
