My Mac
Okay, so when I launch Firefox it gives me a popup that says "A copy of Firefox is already open. Only one copy of Firefox can be open at a time."
I've tried repairing permissions and it still gives me the same error. It only does this on one of three users. Help?
 
Try going to System Preferences, then Accounts. Under the Login Items tab does Firefox show there? Maybe somehow it got setup to launch when you login.
 
Thanks, tried that already too. Firefox doesn't actually startup at login and the little blue dot under the dock icon isn't there either. It launches fine in the other two user accounts, this really has me stumped. I've even tried making sure that the other users are logged off as well.
 
Try using an app like AppTrap to completely get rid of firefox, and then reinstall it. :)

^^ Yeah, it may be an errant lock file or something.

Try this...

Look for a .parentlock file in your FF profile and delete it, if it exists. (It will be invisible in Finder unless you turn on showing hidden files, so either do that or use terminal).

Tried both and I'm still having the same problem. This is really driving me nuts.
 
Who Uses FF? Safari is the only way for me to browse! Gotta love the trackpad gestures!
 
Well I'll probably go back to just using Safari anyways, it's just that it seems kinda weird that this is happening with FF. Plus, I would like to fix this seemingly simple issue anyway.

I know how that use to feel in Windows. All is fine but, WHAT THE HELL IS THIS THING DOING! Can't ignore the elephant in the corner.

you can enable gestures in firefox too (twist left to go to left tab etc) and 3 finger stroll to jump to the bottom of the page and vise versa.

and OP try uninstalling and reinstalling firefox

and cart-wheel right to go forward?

No, thanks.
 
its actually really intuitive once you get used to using it

I'll give it a try and see how it feels. With SL coming out it will be a dead race to see what browser will win my love...and i guess safari is going to get a lot more snappier.
