Oh, I didn't realize those RC versions they were linking to here weren't issued after the official release.
I'm really bad at closing windows and tabs and it's got me into trouble. One problem is I often figure I already have a page open but don't know how to find it so I open it again. Do this enough and you have a LOT of tabs open. :'( It slows FF down very nastily. It's unpredictable on my machines. One moment I get instant keyboard response and the next there's a ~2 second delay. I'm used to it, sort of, but it plays nasty with your nerves.
I watched a couple of videos yesterday on FF 4 and one said they've implemented a find in the address bar for tabs already open, so if I learn to use that (I suppose I have to know what it says in the title bar to utilize this), it may help me with this problem.
Another problem with me is I have a lot of pages I figure I haven't finished with, so I leave them open so I don't forget them. Yes, that's what bookmarks are for, but I have so many bookmarks I don't use them. It does get ungainly. :wub:
