As far as I can tell it's 100% repeatable, every now and then one works the first time on Firefox, but it almost never does. If I use it in Chrome on the same sites, it works. Then I go back to Firefox, and sure enough it doesn't work again. Maybe there's something else making it work for you? I don't know what other factor there could be; some privacy settings in Firefox maybe?
