To add some additional supporting information to this issue:
Redirector seems to work fine on the desktop application, but on mobile it's as described above:
- extension fields and buttons are operable
- redirect rules do not get applied
I've tried a few extensions on mobile (both FF and Chrome versions) with similar results. I know the concept of a built in redirect has been proposed,
though due to these extensions working on desktop, it seems like the mobile failures are a bug.
