Test your mouse buttons, scroll wheel and cursor position — all in the browser.
A mouse tester verifies that every button and the scroll wheel register correctly in the browser. It shows the cursor position within the test area, identifies which button was pressed (0=left, 1=middle, 2=right), and reports the scroll direction and magnitude.
This is useful for testing a new mouse, diagnosing double-click issues, and verifying that the scroll wheel has not developed a skip or reverse scroll problem.
The test area blocks the context menu (right-click) so you can test the right button without triggering it.
Some browsers intercept middle-click for tab management. Try in a fullscreen or standalone window.
