Features & Capabilities

Canvas Course Wiper helps instructors quickly clear out a course they have instructor-level access to, without clicking through and deleting dozens or hundreds of items one at a time.

From a course page, open the toolbar popup, choose which content types to remove (Assignments, Assignment Groups, Quizzes, Modules, Discussions, Announcements, Pages, and/or Files & Folders), type the course ID to confirm, and the extension deletes them using Canvas's own REST API calls under your existing logged-in session.

No API token, no external server, and no data ever leaves your browser. Deletion is permanent and cannot be undone, so it's strongly recommended to test on a sandbox course first.

Requires instructor (or equivalent) permissions on the target course. Works on any Canvas instance hosted on instructure.com.

Is Canvas Course Wiper Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Canvas Course Wiper requires very minimum permissions.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Canvas Course Wiper is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
