Honestly I don't get why this isn't a thing considering that Firefox Nightly for Android already re-implemented this (I'm not sure if it reached the stable release yet). It looks like Mozilla themselves don't think it's that nonsensical.
This sounds like it is either a Windows problem, or a Firefox bug. I guess it's better to wait some Mozilla dev to give their verdict, but this may be more Bugzilla's material than Connect's.
