compat: disabling the geolocation API might result in a bad UX

In our browsers we disable the geolocation.

As a result, navigator.geolocation isn't available, but some sites (e.g., Italian posts) don't handle this error, and will break.

A better UX could be to automatically refuse the geolocation requests. That would probably work with the Italian posts (on Firefox RFP, I just reject the request, it goes to Rome by default, but I can search on my area manually).

We could ask Mozilla if they're willing to rework geo.enabled to make it automatically (and always) refuse the requests instead (and we could even provide the patch, in case).
