Add-ons Manager in Firefox lets you view installed extensions, plugins and themes and allows to disable or remove them. Add-ons manager does wastes lot of space, it’s ok – when you’ve few extensions installed, but if you’ve lot of extensions installed then that space can become precious where you need to scroll down to the bottom to access an add-on, where Cleanest Addon Manager Firefox add-on removes this wasted space without compromising any functionality and makes your add-ons manager look cleaner than before.
This is a nice add-on d(^-^ )
The description for some add-ons are so long that the ‘more’ link (which shows the user more info about that add-on) becomes completely obscured by the ‘compatibility, options, disable, remove’ buttons.
Clicking the add-on section twice though gets you to that more screen.
