FireFox has gotten very slow. The toolbar comes up right away, but it takes ~15 seconds before it will respond. Says, "(Not Responding) if you click ANYTHING on the screen. After that, when you finally can use it, there is a several-second delay before inputting anything via typed command or mouse-click, before FireFox allows any more input. Computer works fine otherwise, it seems to be a FireFox-specific problem. When first installed a few weeks ago, FireFox was very fast.
