convert-manifest-format

Converts between Firefox and Chrome's flavor of WebExtensions Manifest v3.

The following changes may be made:

1. Firefox currently still requires a background.scripts array, while Chrome requires a background.service_worker string.

Note that if you are moving from Firefox, you should import all of your scripts besides the main one so that there is only one script left in background.scripts.

See https://stackoverflow.com/a/75203925/271577 for more background.

2. If the Firefox mode is chosen and incognito: "split" is found, options will be given to keep, remove, or change the value (since "split" is currently not supported).

3. If the Firefox mode is chosen, any options_page value will be converted to "options_ui": {"page": "..."}.

Install

npm i -D convert-manifest-format
