When I test my add-on on about:debugging it work very well. But when I want to add it permanently, I have this error message : Installation aborted because the add-on appears to be corrupt  
I don’t know why ?

It could be for multiple reasons. The “add-on appears to be corrupt” is a catch all for it having some issues.

How did you try to add it permanently? Did you attempt to install it through [addons.mozilla.org/](http://addons.mozilla.org/) or via a local file?

And can you double check that your created extension file is indeed the same version as the one you’ve been loading through about:debugging and hasn’t accidentally forgotten to be updated?
