Hi, first the last update tried a few times over some days to install. Never got confirmation that it has been installed successfully. When I go to "About Firefox" I'm getting the information that I'm using the latest version. Now I have problems, mainly when using facebook (especially when I try to play games through facebook) that Firefox uses enormous amounts of CPU and Memory. This does not happen all the time but at least in 70% of tries. I attached 2 screenshots If this happens I'm not able to close Firefox the normal way but have to kill the process in the task manager. Any quick help would be appreciated. I would also like to know if I'm the only one experiencing this or if it's a common problem.
