Extended Add-ons Manager

The Firefox add-ons menu is not displaying lots of information and provides only buttons to uninstall or disable an extension and open the options if the extension offers any. There is no information about the date that extension was installed or the extension id which are both useful information if you want to analyze or test something.

There is also no way to open the containing folder which really does help as well because it opens the folder of that extension. All extensions are saved in the extensions folder of the Firefox profil folder and the ID of the extension as the subdirectory. It is quite hard to locate a add-on in that extensions directory unless you do know the Id.

The Extension Manager Extended changes the default add-on menu to display those additional information and options.
