How to get information about a chrome extension from the extension url?

Question

I have a chrome extension installed which has a built-in browser(which presumably just loads a page in an iframe). Using this built-in browser I navigate to my locally hosted react app at localhost:3000 , console logging window.location gives an indication that the page is nested within a chrome extension as window.location.ancestorOrigins has a length of 1 with a value of chrome-extension://gjagmgiddbbciopjhllkdnddhcglnemk at index 0; how can I get information about this chrome extension such as its name from this URL or any other way of doing so if this way is not possible?

Answer 1

If I understand correctly, you want more info about an extension with an ID saved into this URL in your question.

So there is a simple way to do it using extension API.

1. You could use get method from management API . It has id param in the query so that you will receive a single element as a response.

2. If you want to pull data about all extensions that are installed you could simply use getAll method from the same API I showed before.

If you receive this ID in content-script. Then use runtime API to send this ID to the MV3 service worker and parse it as described above.

MV3 API provides promises. I showed an example for Chrome API, but it wold work for other common browsers. Also, you could find this method on the extension API polyfill.

Hope this would help.
