hi guys i am enjoying APB for a few years at Firefox. my question is, sometimes it happens that after installing a new version of Firefox, after that i enter a certain site but APB wont work there,(although it is enabled for that site), and only after refreshing that site (sometimes even need to refresh twice), it blocks whats needed, i happens now at Firefox 46.0, and i remember it happened to me a few years earlier, (maybe like FF 3X).
any1 knows why does that happen and what to do to salve it? TY!
