Drawing Tool - By Mr.Bear 作者: Mr.Bear

Drawing Tool lets you draw and annotate directly on top of any webpage using an overlay canvas. You can sketch freehand, add shapes, arrows, and text, adjust color, size, and opacity, undo actions, or clear drawings at any time.

The drawings do not modify the webpage itself and disappear when the page is reloaded. The sidebar stays open while switching tools, allowing quick access during work sessions.

This add-on is useful for homework, teaching, presentations, screenshots, and general work tasks where visual explanations or temporary annotations are needed.
