Support.
I use firefox and every 5 seconds if freezes for about 2~ seconds.
It's really weird, because it only happens on browser (and i NEVER play on browser, just tried today)
I think it's because there are two programs (in my case,) firefox.exe and java.exe which are both running therefore firefox is running the java therefore using more CPU than normal sharing it out between the two therefore causing less priority to java.exe making it laggy.
IDK. My theory anyway...
