Features & Capabilities

This is a browser extension which changes the client-side assignment due dates on Canvas. It will change each due date to be between 1-72 hours earlier than it is actually due, to aid in getting homework in on time. It does not change the actual assignment due dates, rather it just edits what is visible on the client side.

The goal is to help reduce procrastination on homework assignments - many of us will procrastinate an assignment up to the deadline, then submit it a few minutes or hours late. This fixes that! You won't know exactly when the assignment is due, so if you are a few minutes late to the randomized due date, you'll still be on time for the actual thing!

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