Is it possible to force the popup to open? Or to have a notification symbol?

[Phil Oxnard]

I want my popup to open up when it detects a specific state change from the server. My service worker can detect the state change, but I don't know if its possible to relay info from either the server or the service worker to the popup if the popup isn't already open.

From  https://developer.chrome.com/docs/extensions/reference/action/#method-setPopup

An action's popup will be shown when the user clicks on the extension's action button in the toolbar. The popup can contain any HTML contents you like, and will be automatically sized to fit its contents. The popup cannot be smaller than 25x25 and cannot be larger than 800x600. The popup is initially set from the default_popup property in the action key in the manifest.json file. If present, this should point to a relative path within the extension directory. It can also be updated dynamically to point to a different relative path using the action.setPopup() method.

It would therefore seem that the answer to your question is no.

However, you can change the appearance of the browserAction icon and its tooltip.

You can change the icon or place a badge on it.

This way the user will see the change and will be motivated to activate the popup manually.

If you don't want to change the appearance of the icon, you can always create a notification when needed.

Roberto’s answer is the most reasonable solution available at the moment.

I faced the same problem. Did you find the right code ?

You can add your UI to the web page using a content script.

[Tyler Durden]

Yes, of course I can. But I want to pop up on this page or repaint the icon in a different color, but I can't do it.
I'm sorry if this question is very stupid

Yes, you can do it easily: show your UI inside the page (in an iframe for more isolation) so it'll look exactly like an open popup. Additionally change the icon via chrome.browserAction.setIcon. Many extensions do it like this. The only other solution is to open a separate window with the UI inside, but it's worse.

For an example of an extension that changes the icon at runtime, see https://github.com/GoogleChrome/chrome-extensions-samples/tree/main/api/action
