I have been having problems with unresponsive scripts, FF using way too much cpu and very slow internet browsers. I did some investigating, disabled all of my add-ons and found the culprit. OpenH264 video codec has no option to ask to activate...which is weird, so I set it to never activate and problem solved. Please fix this Firefox. I noticed there are a few other add-ons that don't have the ask to activate option...why is this?
