It looks like it is working on Opera Dev (just tested it) and if it is showing on Opera 25 then you are correct.
Any thoughts as to when the next Beta release is going to happen? This same problem is also occurring on udemy.com (cannot login because it does not display the popup).
I thought about switching to the Dev channel but was a little worried about the stability of that channel.
Thanks!
And here is the screenshot from udemy.com. Tested in both Opera 25 and Opera Dev 27.
At this point, I don't think it's an Opera bug. But maybe...just maybe, something specific to your version. Maybe you've got pop-ups blocked? Maybe you've got an extension that might interfere with the functionality of those sites, since it's blocking something? I don't. I'm just saying. But, as you can see, this doesn't seem to happen to everyone.
Also, I think you should switch to Dev channel. Opera Dev is rock solid.
Actually, to be honest, I don't think I ever tested any unstable version of Opera. The crashes that I've been encountering were not Opera bugs, they were all third party bugs (Adobe's, to be exact). And I've been using Opera for many years now. So, to me, it's not a matter of stable vs unstable, but only a matter of features vs...well, the lack of those features. :)) For example, Opera Sync was, to me, one of the main features and the main reason for switching to Opera Dev. Maybe you'll find some features that YOU like. So...yeah, go ahead. Give it a try.
I'm really curious how can one fully uninstall Opera from their system. Meaning app and data. I had this question for a very long time regarding Mac applications. Some of them can be simply moved to Trash, and that's it. But some of them, Opera included, will leave some data behind. And that data might interfere with newer installations of the browser. So removing that could be quite important if you want a really clean install.
