Add-ons Development
#1

I made extension according to borderify tutorial and I zipped it with web-ext built (looks like it only make zip file with all addon files). I tried to install it by installing it from file and I got error:

Error when installing my own Add-On

This addon works fine when added with about:debugging.

Based on the error you don’t have an ID set and are using something, that requires one, see https://developer.mozilla.org/en-US/Add-ons/WebExtensions/WebExtensions_and_the_Add-on_ID

It’s just borderify from tutorial :slight_smile:
But it’s not signed so I’ll give it a try.

Just added

"applications": {
    "gecko": {
        "id": "borderify@example.com"
    }
}

and it helps. Thanks a lot

Tip: Signature checking in about:config must be false
