I just recently decided to switch to Firefox from chrome because I was sick of chrome's adblocker never working. Unfortunately, whenever I use Firefox, it will randomly freeze my entire system so I have to do a forced shutdown by holding the power button. When it freezes I can't even move my mouse let alone open task manager to end Firefox. Any help is greatly appreciated because I really like Firefox but it is annoying having to keep restarting my computer every 20 minutes or so. I notice that usually freezes when watching videos on YouTube, although not always. I am using Firefox 30.0 with Windows 8

Something similar happened to me at one point, and I found out that one of my RAM chips had gone bad. The way I found out was from scanning with Memtest86. Its an ISO file that you print onto a CD, then the computer will boot from it. After replacing the chip it has been running smoothly ever since.
