Hi everyone,
I am writing to you because we are trying to publish an extension already available for Chrome on FireFox.
During debugging we get the error: invalid manifest.
After several attempts, we tried to add the example Add-ons shown in the official repo on GitHub.
Unfortunately, even these, all those tested, give the same error.
Instead, when trying to publish the Add-On in the Marketplace, we receive the error Manifest.json not found, even for all the published examples
We simply zipped the folder containing the code, as we did for Chrome.
You can help us?
