My problem is this: I have a software installed with Wine (Brain Explorer 2, it's free); certain functions of this software requires using the browser (in this case google chrome; firefox isn't an option since this needs flash player...). Then, Explorer opens browser. When you are browsing in the website, there is an option that loads data from browser to software, then the browser ask for external protocol for aibe:link (aibe is for Allen Institute Brain Explorer, I suppose), that ends on launch xdg-open, which as far as I know it handles the default apps.
So I guess must try config the default apps for aibe links, but honestly I'm lost. The most I figured is that is similar to magnet links with torrent. Of course on windows there is no such a problem since is designed for it. But how I make this work here on Ubuntu?
