Installed it and reset my canvas but nothing changed

THE best extension for students that use Canvas. Saves tons of times when redoing quizzes or assignments, and the lights out mode is the best. Seems to function pretty well and be pretty power efficient.

Is CanvasPlus 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.

CanvasPlus requires very minimum permissions.
