Hi all, I usually have about 5 windows open, just regular websites. Suddenly my fan goes beserk and I look at the processes where on one firefox.exe the CPU is at 40-50 and everything slows to a crawl. When I press end process, it shuts down, the fan stops and browser speed goes back to normal. What is running in the background and how do I stop it?

Thank you
