I went from Chrome to Firefox 16 not too long ago, was nice till i went to youtube and the videos keep freezing firefox for a few seconds while the audio continued. Its not my PC for sure, latest video drivers, latest flash, latest firefox version, nothing worked. I decided to go with Opera and i've been satisfied so far but its really bugging me that firefox had that only flaw for me. Anyone would know why? GTX460 and Phenom X6 1090T, SSD drive. I dont think its hardware specs, i mean i run all modern games at near max quality, its not going to be youtube videos that will test this hardware, most likely an incompatibility between firefox and flash.
