This extension is the source of many errors when logged on to cloud.google.com

Several extensions were disabled in Firefox while trying to track down the origin of the

"Oops! An unexpected problem occurred. Please refresh your browser."

messages when logged into cloud.oracle.com

Firefox 95.0.2 64 bit, the current latest version, on Windows 10.

This consistently occurs when choosing items from the menu at cloud.oracle.com

After disabling "Disable HTML5 Autoplay", the errors stopped.

Checking the Firefox Console, the error was always this url:

view-source:moz-extension://86436a12-f1b7-4665-ba83-101479f2641a/js/content_script.js

and this bit of code:

function injectScript() {
const domain = window.location.hostname;
const scriptFile = domain === 'www.youtube.com' || domain === 'gaming.youtube.com' ? 'youtube' : 'inject';
const script = document.createElement('script');
script.src = browser.extension.getURL(`js/${scriptFile}.js`);
document.documentElement.appendChild(script);
}

This code may be here due to numerous complaints about compatibility with youtube.

In any case, I have removed the extension, and the problems went away.
