Filtering extensions like AdBlock, uBlock, and AdBlocker Ultimate may interfere with GoGuardian Teacher. If a filtering extension blocks parts of Teacher, you may see students as “Student Offline” and have trouble using Commands like Open Tab or Close Tab. GoGuardian Teacher notifies you when it detects ad-blocking software in use.
If you suspect an ad blocker is causing trouble, open GoGuardian Teacher in an incognito browser window. Browser extensions typically do not load in incognito mode, so incognito is a good way to test and compare.
