The address wasn’t understood (how to redirect URL to software on computer?)

Posted

When I click on a link which is: osu://b/1006632

Firefox says:

The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (osu) isn’t associated with any program or is not allowed in this context.

You might need to install other software to open this address.

I have the program osu installed on my computer. How do I make the address in Firefox redirect to the osu program?

In that address, osu: is the protocol. Firefox usually discovers how to handle protocols (those it doesn't display itself) from the Windows registry. Usually programs are pretty aggressive about adding themselves to the registry, but you could check with the program you're using whether you need to take any extra steps to trigger that.
