Chrome extension closes when I click on the page

Question

As stated in the title, the Chrome extension I've been developing closes whenever I click on the page, and I noticed that this happens with all the other extensions that I have.

I really have 2 doubts:

1. Whether it is actually possible to leave the extension open regardless of whether the user clicks the screen or not;

2. If it is possible to force the extension to open via Content_Script;

Answer 1

I presume by "extension closes" you mean that a popup in your extension closes.

This is indeed normal behavior that you cannot override if you click away.

It's also not possible to open a popup from your code in Chrome.

So if you need some UI that co-exists with a page you interact with, you'd need to inject it into the page itself. Probably using Shadow DOM so that the page's styling doesn't interfere with yours.
