On the Chromebook, the system may appear to be launching LockDown Browser with quizzes that do not require it. You may close out of LockDown Browser windows, and the quiz will open, or you may turn off the browser extension until you need it for the next test.
To turn off the LockDown Browser extension: type Chrome://extensions/ in the URL address bar in Chrome. Locate the LockDown Browser Chrome Extension, and toggle it off.
To activate it again later: type Chrome://extensions/ in the URL address bar, and toggle the extension on.
