I presume it would in a similar fashion to Zoom on Mac (I have't used Windows in a while) where Firefox prompts you to open a Zoom meeting link in another application (i.e. Zoom), which you can ask FF to remember so the link is automatically opened with that app next time.
Hmm. I think the destination app has to support that directly though, doesn't it? http: links should automatically go to your default browser, of course, but that would require that this new browser is not your default browser. Maybe you could hack around it in some way; I'm not a native desktop app developer so I don't really know just how much leeway one of those has within the host system.
