In my experience it's subtle bugs that don't appear on one platform but do in the other. webcompat is great for true deviations from the spec but there are plenty of cases where things work for no good reason and it's a chore to figure out why. I'm also a bit curious why blocking Firefox is preferred versus stating which browsers are supported.
