Is the flash update 11.3.300.265/ firefox13 update issue ever going to fixed?

About a month ago I updated firefox to 13 and flash to 11.3 and I had the common issue alot of users had of firefox crashing. So as recommended I downgraded to flash 10.3 ( I don't have real player so I knew that wasn't the issue). 4 weeks passed and I'd read online that the issue had been fixed so I updated my flash again to 11.3 . As soon as I did i started having problems with flash content again, it's not crashing like before but firefox won't display flash content like my facebook games it just sticks and won't work ( these flash games play fine on IE with no sticking so I know it's a firefox / flash issue rather than a facebook issue also the games are all made by different company's which also suggests it's not a game developer issue but the main reason I'm quite sure it's a firefox / flash issue is the fact it happened as soon as I updated to flash 11.3 again), i can watch videos but not play flash content games. I've tried firefox in safe mode (addons disabled) and I've tried uninstalling and reinstalling flash 11.3. Neither made any difference What should i do ? do I need to downgrade to flash 10.3 again and if so is the issue ever going to fixed so I will beable to upgrade to 11.3 and stay on it and not have to keep downgrading flash version ?
