Hey,
my first Addon for Firefox does only work with the Developer Edition of FF.
It is available in the Official Addon Database.
If you load it there will be no buttons, but you can modify the settings of my Addon.

The two Buttons should be in the upper right corner, but they don’t appear
PS: It’s my first addon and I am new at developing addons.
Thank you!
