Respondus Lockdown Browser (Student Guide)

Your instructor might require the use of Respondus LockDown Browser for certain quizzes in your course. LockDown Browser is a locked browser used specifically for taking quizzes in Cougar Courses (Canvas). It prevents you from printing, copying, going to another URL, or accessing other applications (like Word) during a quiz. If a quiz requires that LockDown Browser be used, you will not be able to take the quiz with a standard web browser. Your instructor may also have enabled Respondus Monitor, which uses your webcam to record you while you take the quiz.

Before Downloading


You cannot download LockDown Browser from an external link, you must do so from the Cougar Courses quiz/exam that requires it. Unfortunately this is only possible once the quiz is available. This is why we recommend instructors create a practice quiz that is available the whole term so that you can download LockDown Browser ahead of time and ensure it is working correctly at any point. If you do not see a practice quiz that requires LockDown Browser in order to download/test ahead of time, please contact your instructor to request they create one.

  1. Open Firefox (PC) or Safari (Mac).
  2. Login to Cougar Courses.
  3. Go into the course and go to the quiz that requires LockDown Browser. Click the "Take the Quiz" button.
  4. Click on "Download Respondus LockDown Browser."

Before Using

  • Be sure you are not using AVAST anti-virus program. The latest version of AVAST blocks the LockDown Browser and it will interfere with using Lockdown Browser until you remove it.
  • Close all other programs, including Skype/Zoom and other chat systems, which may be running in the background. You may need to disable third-party plug-ins or tools enabled in Firefox.
  • If Monitor is enabled, check your webcam setup to make sure your webcam and mic work.
  • Take a practice quiz, if your instructor has made one available, to ensure LockDown Browser is working correctly.

Launching LockDown Browser

  1. Close all open programs.
  2. Locate the “LockDown Browser” shortcut on the desktop and double-click it. For Mac users, launch “LockDown Browser” from the Applications folder.
  3. If prompted, either close a blocked program (e.g. screen capture, instant messaging) by choosing Yes. Or, close LockDown Browser and close the blocked program before restarting LockDown Browser.
  4. If prompted, choose "Canvas" from the dropdown menu.
  5. Log into Cougar Courses.
  6. Navigate to the quiz within the course and begin the quiz.

Problems Before Starting the Quiz

  • First, try restarting your computer.
  • When LockDown Browser does not start up or there are issues accessing a quiz, it is sometimes a security setting or another application interfering with LockDown Browser:
    • Ensure all applications are closed including background applications (except security).
    • Disable or remove third party apps or plug-ins from Firefox.
    • Make sure only one security application is running on your system.
  • If able, click the Help Center button at the top of the LockDown Browser window.
