contentScripts.RegisteredContentScript
A RegisteredContentScript is returned by a call to contentScripts.register() and represents the content scripts registered in that call.
It defines a single function unregister(), which can be used to unregister the content scripts.
Note: If this object is destroyed (for example because it goes out of scope) then the content scripts will be unregistered automatically, so you should keep a reference to this object for as long as you want the content scripts to stay registered.
Methods
unregister()-
Unregisters the content scripts represented by this object.
Examples
This code toggles a registered content script on a browser action click:
js
let registered = null;
async function register() {
registered = await browser.contentScripts.register({
matches: ["*://*.org/*"],
js: [
{
code: "document.body.innerHTML = '<h1>This page has been eaten<h1>'",
},
],
runAt: "document_idle",
});
}
function toggle() {
if (registered) {
registered.unregister();
registered = null;
} else {
register();
}
}
browser.browserAction.onClicked.addListener(toggle);
