Communication between bundled ressources and Safari App extension

Hi,

I work for Dashlane and we currently have a legacy webextz extension with ~85k users. We are trying to port our legacy webextz extension into a Safari App Extension app.

However, we are facing a blocker.

Our issue:

1 - Our extension injects a content script that creates an iframe in the page

2 - The source of the iframe is an HTML resource embedded in the extension (safari-extension://com....i/index.html) that requires a javascript file (also bundled in the extension).

3 - With the new api, we don’t have access to the safari object inside the iframe.

ReferenceError: Can't find variable: safari

It means that we are not able to communicate safely with the background of our extension with the following function:

safari.extension.dispatchMessage

Without this feature that was present in the legacy extension, we cannot ensure that the user’s data is safe, thus migrate to the new safari app extension.

I am available to help you move forward with this issue (mail, screen share, phone call, anything), this issue is critical for the company I work for, and our Safari users.

Best regards,
