The problem is caused because Opera is using a handler to manage a web-mail application automatically. You can stop this behavior from happening by going to Opera -> Preferences -> Privacy & Security, then in the Handlers section delete any association with a webmail application in Opera.

Save preferences and you will see that the problem is gone.

Have a great day!
