@leocg Nope. Some other users confirm that there's a problem with Opera not dealing correctly with not only magnets, but any other protocol handlers, and that the developers are aware of this.

So let's hope it gets solved soon, and that we also get back the file-types association advanced option too.

@leocg It did existed in Opera once upon a time. I don't really know when it dissapeared, all I'm saying is that it's a questionable decision to let this capability out of the advanced options group, as it was before.

Look, I get this is a free software and I'm very happy with Opera, I think it's a fantastic browser, but not letting the user set their own file-type associations sounds a little bit absurd to me. And I'd like this decision to be reconsidered.

Besides, there's a problem in the way that opera handles certain file types or links, like magnet links... Is there any workarround, at least?

Yes, that's the point. So, you are confirming that this option has been purposelly removed from the latest Opera versions...

Any idea why? I think that this is a much needed option, specially if the preconfigured file-type associations are not working as supposed.

So, where are the file-types association options? I see no means to edit the MIME settings...

Also, every time I click on a magnet link I get a message about opening it with my default bittorrent client. No matter if I permit it or not, the netx time I get the same message. It's almost like there are no file-type association preferences. Thats why I want to check the current associations.

Oh, and also, no trace of MIME settings in the Opera help page (and I used the F1 shortcut).

Same error here. Check this post:

Yes, I've been trying to sign in using my user name and password, and I get this message every time the browser checks the credentials:
Connection Error. Cannot sync data
Opera said the problem had been solved 5 months ago. Now sync is not working again. Please Opera, check this because it happens both in iPad and iPhone.
