Step 2

Open a new tab, and open the first chrome extension bookmark. Now click the chrome://kill bookmark and now spam the chrome://hang bookmark while also spamming the reload button on your keyboard. Do the same thing for all the other chrome extension tabs. After that, try looking up something random. If it doesnt work, turn off your chromebook and do this step again. If it does load after doing all that, then you have successfully crashed the extensions!
