today I migrated an old extension to the new WebExtension API. Testing was ok, so I uploaded it and signed it on AMO. It’s a self hosted add-on. So I downloaded the signed file and tried to install it.
Installing on Firefox 55.0.1 on Linux was fine, no problems.
Installing on Firefox 55.0.1 on Windows 7 always force a corruption error and says signing was invalid? Anyone with such a strange behaviour?
