How do I uninstall LibX?
Go to the menu Tools -> Add-Ons. (In Firefox 1.5 or earlier, this entry was called Tools -> Extensions.) Select the LibX entry in the list. Click “Uninstall” at the bottom left (it looks like an X). Restart firefox. Note that short of uninstalling, you can also disable LibX in the same dialog. (Requires a restart and makes all of LibX’s functionality unavailable.) If you simply wish to not display the toolbar, you can accomplish this by selecting the menu View -> Toolbars -> LibX. An even quicker way is to right-click on a navigation bar button, such as the refresh button, and to uncheck the box “LibX”. The IE version can be uninstalled like any Windows application in the system panel.
