Watching videos until the end or only 30 seconds and no problem in chrome: i get credited. The problem is whe i use firefox, no way to get paid even using firefox in other computers and/or locations.

I am not being credited watching videos in BitcoinGet, Coin Tasker or CoinTuve.tv if I use firefox. If I use Chrome I get paid. Whats going on with firefox? Obviously is a briowser problem but I checked my firefox settings and nothing is wrong there: cookies are allowed always. someone has an explanation?
