Fast? Good.
Lately I’ve been having difficulty with FF both the stable 4.xx whatever, and the beta 5 just simply locking up. There they sit, unable to load a page. I have to close the browser, and go into the task manager to close whatever FF function is still running.
Then, out of frustration, I open IE and it screams compared to FF. I hate that. I want FF to scream that fast.
I'll give FF5 a whirl for a bit. If it ends up more like FF4 than Chrome 11 or IE9-32bit, I'll stop using Firefox again.
