Redirecting alternative URI schemes (mailto:, tel:, etc)

[axelerometer]

I would find it useful to redirect alternative URI schemes: mailto: and tel: URIs, redirecting them to a web URL. Seemingly this is not supported by Redirector.

I can create a redirect rule with a pattern such as ^tel:(.+)$, it applies correctly in the "Example result" preview, but actual URLs on sites don't seem to be handled.

Any ideas/suggestions? I am using Firefox.

I think it would be worthwhile too. The big question is if that's supported in Web Extensions. IIRC, last I looked (which was a long time ago), that functionality wasn't supported by Web Extensions. But Web Extension technology is constantly improving, so maybe it's possible now. Does anyone know?
