Hello @DeletedUser
Thank you for contacting the Instructure Community. We're sorry to hear you've been experiencing issues with Chrome extensions.Unfortunately no, we cannot ban extensions on browsers for all users across out platform. However, if your students are using school computers or they are taking these tests on the school wifi - your school could ban them. If the students take them at home, then you will want to explore proctor services available through Canvas like Lockdown Browser or Proctorio. These can record the students' screens and/or webcams to ensure they are not cheating. There are others as well and many schools use this and there is a good likelihood your school already pays for it. Please reach out to your school directly to discuss options.
