|Admin Bar Unlocker - Installed on every website I run|
I'm sure Joomla has a good reason for locking the admin bar, but I certainly don't know what that is.
This extension saves me so much time and headaches. It allows me to open another tab in FF for say, the article or section manager, without having to leave what I'm editing. Great when I need to clean the cache, too. Such a great extension!
