Firefox does not handle osu:// schema correctly

I have installed a game program that accept and handling such a `osu://` schema. URLs with such schema is provided in its site. By clicking it, browser would call up the game program (according the schema handler setting), then pass the URL to it.

This mechanism works fine, except it is a side-effect.

By clicking the osu:// URL (such like: osu://b/355852), Firefox would open a new window, but weirdly covered it into a http:// URL (like this: http://osu//b/355852 , which I copies from the new-tab's urlbar.).

This problem is not a big-up, but truely ... odd (because it appears only on this schema, the others, like ftp, ssh, irc..., work fine). So that I am interested in it. Is any clues to why this happens?


Hints:

  • Schema handler is registered fine, because game program catch the URL correctly.
  • Using FF Developer Edition 51.0a2 (2016-11-09) (64 bits), on Windows 7
  • Tried disabling all add-ons, problem remains.

Which Firefox version are you using? Please provide the full version number. What is the game you are talking about? Have you contacted its support?

Hello, I've make further tests.

Such problems reproduce when I am using (such as) IE. Like that way: 1. Browsing a page contiains osu:// link, click it; 2. Game program is called up, it is a cold start so it takes seconds; 3. After game started, the http://osu/foobar is launched on Firefox.

As firefox is set to be my default URL handler, so it must be someone invoke such a malformed URL. Obviously clearified, it is not FF's guility.

I am logging my environment to find what on earth.

Thanks for your delightment.
