Firefox is my go to browser but as of late it is forcing me to use Safari as a default. The issue I am having is firefox is causing my system to run to hot causing the fans to go nuts. Even if I have no other applications open. As soon as I close the browser the system cools and fans resume to normal. Certain websites have a bigger effect than others on the overheating issue. The odd thing is other browsers have no issue running the same pages.
