How to pause/resume execution of js extension script?

Question

JavaScript

Good afternoon
Tell me how to implement off / on script execution in the active tab.
It is desirable that without additional. windows. Those. clicked on the extension icon - it's on. Pressed again - it is off
Unfortunately, we could not find similar topics. Please help:
Scheme of work:
The page is loaded The
script is loaded
If the extension is on, then the script is executed (
If the extension is off, the script is not executed (if the user is on, then the page should reload and the script should be executed)
I think the meaning is clear? Similar to pausing and resuming adblock
