Perfect for what I want to use it for.
Simple yet good tool!
Worked well for what I needed it for. Good extension.
I used it to measure angles for directional radio transmissions in Google's My Maps with line plots. Simple to use and works well for me. Thanks, Ben!
I would only add the option to show angles bigger than 180, and not change them automatically to the smaller angle of the circle.
Awful. Could not move it across the screen. When I tried, it disappeared.

Very buggy. Couldn't move protractor, when I tried it disappeared. Tried again, tried redownloading, wouldn't work.
I used it for measuring polyhedrons in 3D rendering. It also helped me with my math homework.
