How do I get rid of this wretched thing?

@khbiz Thanks that worked

@khbiz I think I have sorted it - I had not set my email client to default, seems it was nothing to do with Opera at all. Don't know why I didn't have this problem with Firefox before moving to Opera
But interesting I couldn't find "Default email reader" in my opera preferences (Mac for Settings) at all

How do I just download PDFs. Opera tries to load them and takes ages and I can't find a way round it. I'm using opera on a mac - perhaps opera is not the best browser for a mac?

@leocg Having the same problem - I've looked but can't find anything. I just want Opera to refer to my usual email client
