When are opened differents webpages ( not many pages, even with 2 ) Firefox uses 99% cpu and doesn't load pages anymore until i restart it or kill the process. ( sometimes i need to kill it because the process never finishes ). With a process viewer software, i can see this file using the CPU ( mozcrt19.dll ). This is an intermittent problem, there's no a specific page.
