Hi, since yesterday, every time I try to open Firefox browser, it says that is already open and to close it first. I did that many times, also by “ end task” in task manager... I re started the computer ... I also tried to run Mozilla as admin but nothing. I can’t use it anymore. Is it possible is a malware ? There is any “ normal “ way to fix it as a regolar user like me not a guy who does really know well how to tasks and do things with a computer ? Thanks a lot !!
