Steps to reproduce:

In Fenix, visit https://github.com/mozilla-lockwise/lockwise-addon/releases and long press on a .xpi file found in any Assets section of each release.

Actual results:

Nothing happens. No onExternalResponse event is fired.

Expected results:

The onExternalResponse method should be called and the file should download.

Gecko might be short circuiting .xpi links or GV might be ignoring some XPI install event from Gecko. But downloading untrusted third-party extensions in Fenix is a very low priority since Fenix+GV doesn't even support installing extensions from AMO yet.

I can reproduce this download bug in Fenix and Focus+GV. Downloading the xpi in Fennec triggers a warning dialog: "Blocked add-on. Firefox prevented this site (github.com from asking you to insall software on your device. DISMISS / ALLOW".

That suggests this bug is either a bug in GV or Fenix's download manager.

Tiger says Fenix's download manager never gets executed because GV never calls onExternalResponse. So this must be a GV bug.
