Magnifying Glass от Joue

This extension transforms your cursor into a magnifying glass, enlarging the current object beneath it. You can adjust the size of the lens and the scaling value through the right-click context menu over the action button.

To turn off the magnification and revert to the default cursor, use the left-click or the Escape key on your keyboard.

When the extension is active, the action button appears red; when it is inactive, the color is blue.
