It makes the browser slow (like dial up) if I leave FB open for maybe a hour or so, never timed it. All other pages are good, if I don't touch FB I am good for the whole day. I think it is a prob. with a script the FB page uses. I don't have its name sorry, it is like a memory leak, but why would just a certain page cause it? The FF people know about it & I did what they said on the forums & it just slows down now instead of crashing a few secs after the slowness starts.
