Flash causes Firefox to slow down and even freeze (and on a gaming laptop, too). How to fix this?

Posted

Every time I use the Flash plug-in (for videos on YouTube or PutLocker or whatever), FireFox just slows down a lot and even freezes. It happens very often now and it's really annoying.

By the way, I am using a gaming laptop so I am not sure why I am having these problems. My Flash plug-in and firefox are updated to the latest versions, too.

My specs: Windows 7 Home Premium Intel i7-2670QM CPU @ 2.20GHZ (8 CPUs) nVidia GTX 560m 3GB vRAM dedicated 16GB RAM
