Hello,
I just have finished my first extension. If I install it temporary for debugging purposes it works. After uploading to AMO (only for private use) and a few adjustments it was signed without any problems. Then I downloaded my extension and tried to install it in Firefox. But I always get the error message: “This addon could not be installed because it seems to be damaged” I dont’t know the exact wording, in German it is: “Dieses Add-on konnte nicht installiert werden, da es beschädigt zu sein scheint.”
I don’t understand why it is not working. Any help appreciated.
If more information is needed please ask me.
Thanks a lot in advance.
Kind regards,
Bjoern
