Add-ons Manager Rated 5 out of 5 stars
Add-ons Manager in the list does sound like what I'm looking for, but it's not there.
I'm using FF28.0 on Kubuntu 13.10.
I keep the Addons Manager as a pinned tab, but it doesn't show up in the list so I have to click it or use the keyboard shortcut (I finally memorized it, but forget to use it most of the time).
Thanks for the Addon
