@leocg yes I have now disabled all extentions and still figuring out which one is causing it. Definitely an extention for me. Thing is I haven't installed new extentions for months so I think one of them updated with a malware.

started yesterday
Linkedin random URL keeps opening new windows while broswing or even just watching youtube
I have run malwarbytes and I have ESET Smart Security running.

I cannot find a way to stop it from happening.

Please if anyone can help me to stop opera opening a new windows automatically?
would be so helpful if opera would show what opened the webpage then I could eleminate it.

Thanks in Advance
