I am about to submit a new addon, in the WebExtension format. It’s my first attempt, so I am a little lost in the process.
I have tried the following step:
web-ext sign --api-key user:… --api-secret …
but get the following message:
Server response: GUID is required for Firefox 47 and below. ( status: 400 )
FAIL
Can anybody help me with this last step?
Thanks
