Every time I open Firefox, since the last update, one of the exe programs begins using billions of cpus and causes my computer to freeze. It is not Malwarebytes or anything else, as I never had this problem before. While Firefox exe programs in general use too much, none has ever gone above 500,000 cpus before. After I mentioned this in a few places, it got better, but it started up again since the last update was posted, even though I have not downloaded it. Perhaps it has something to do with putting out updates? The only cure I have found is to open my Task Manager, and end the process that is gobbling up all the cpus, and after I do that, Firefox runs just fine. Somebody has screwed up with an update and this needs to be fixed, it seems to me. Sometimes, I can't even open my Task Manager. I am using Windows 7, yes, on a PC. And, by the way, this doesn't happen on my laptop, but I have not downloaded any updates on it, and will not. Also, someone mentioned changing a setting on how resources are used, but there are no advanced settings available anymore.
