So is there no way to disable the "leave site" pop up message? It is quite annoying.

How can I prevent the "leave site" pop up message.Opera for Mac
A similar discussion (now closed) suggested enabling the flag:
How do I do that on a Mac? When I go to that page, I do not see such a flag.
Let me add that Firefox does not do this, and I get the message on a number of sites, so it appears to be Opera and not the site that is generating the message.
