Per the Mozilla [manifest spec](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/browser_specific_settings), I can add an extension ID with: ```json "browser_specific_settings": { "gecko": { "id": "addon@example.com", "strict_min_version": "58.0" } } ``` How do I add this using this plugin? Thank you for this great tool.
