I have also been having all sorts of problems with Firefox. They sure have gone downhill as a browser. I think they should go back to keeping it simple.
One problem I have been having of late is at neobux. When I'm trying to click my mandatory daily clicks sometimes I have to click the same site twice and almost always, when I've earned the money and closed the window, I have to reload the ad page once or twice just to get it to load.
Maybe it is neobux doing it because I have just started to trim down my rented referrals since I was sending all that money to NB just to maintain them. So since I have started reducing my RRs this whole problem has started.
I'm also getting FF problems on other sites so I don't know who is to blame. It is very frustrating
