Limits of a browser: what this can't tell you
  • A flagged press suggests a fault; it doesn't prove one. A fast finger can trigger it too, which is why you single-click slowly.
  • Mouse firmware and drivers filter some bounces before the browser sees them, so a fault can hide here and still appear elsewhere.
  • Times come from browser events, which some browsers round for privacy. Treat them as good to about a millisecond or more.
  • Side buttons may make the browser go back or forward. If so, come back; the result may clear.
  • The 80 ms default is our rule of thumb, not a standard. Adjust it.

Single-click the box and every press is timed, logged and flagged if it comes too soon after the last.

How to test your mouse for double-clicks

  1. Rest your finger and single-click the box slowly, about once a second.
  2. Do it at least 20 to 30 times for each button you're worried about. The fault is often intermittent.
  3. Read the log. Red rows came sooner than the limit.
  4. Follow the repair steps if the fault line appears.

Reading the interval log

  • Each row shows the time since the last press of the same button.
  • A slow single-click pattern shows gaps of hundreds of milliseconds. A bouncing switch adds gaps of a few tens of milliseconds or less.
  • One flag is "possible". Three or more is "fault likely", and so are two when they make up at least 5% of ten or more presses.
  • You can lower the limit to explore if you click fast on purpose. It goes back to 80 ms on reload, and only a run judged at 80 ms can count as Passed on your report.

Common questions

What is a double-click test?

It checks whether a mouse registers two clicks when you press once. It times the gap between presses, since a worn switch "bounces" and sends a second press almost immediately.

How can I test my mouse for double-clicks?

Single-click slowly on the box above and watch for red rows in the log. Red rows at a slow pace point to a faulty switch.

Why does my mouse double click when I click once?

Usually a worn switch, sometimes dust or a system setting. Clean around the button, try another port, and raise debounce in the mouse software if it has one. If it persists, check your warranty.

Is this a click speed test?

No. It looks for faults rather than speed, so there are no scores or timers to beat.
