Hi,

We have an extension in where the background script is creating an object (with operations) that we somehow wants to get a reference to from the popup script.

Is this supported ?

No, it is not supported.

In MV3, the background script is a service worker that is not always active. You should exchange messages through extension api or standard web api. Or you can save data to storage in background and read data in popup.

PS: chrome.extension.getBackgroundPage() and chrome.extension.getViews() can't get the service worker in MV3.
