@avl Depends on what you consider special. Someone who isn't me has tampered with my browser. (Yours, too.) That's special enough by my standard. I want to fix it and make sure it never happens again. If I can't do that, I will get rid of Opera and think seriously before downloading it again and starting over.
The same thing once happened in Internet Explorer. Microsoft's product support people provided a solution immediately (except for the hold waiting for a human to become available.) Unfortunately, that was something like twenty years ago, when one could still hope for effective product support, and I have no idea what it was or whether it would apply to Opera now.
