Firefox ran at 102% of my CPU today, according to Activity Monitor. I’m not sure how that is possible, but the audible increase in fan activity was the first indicator. The same thing happened at work today too. Then, I thought it was because I had so many tabs open. And when it happened just now, I discovered I had opened a tab with a movie in it. But then, I clicked on Help to see if there was a Feature Request button, and I saw that Firefox was downloading an update. Still, it brought my processor to a halt with whatever it wanted. It makes me (once again) consider switching to something Mac-native. Oh, how I would miss my extensions.
