Mouse questions, fixes and result guides.
Practical answers for common mouse problems, confusing results and setup questions — with a direct path back to the live test.
How do I test if every mouse button works?
Use the focused mouse test area and press left, right, middle and side buttons one at a time. A button should produce a consistent browser event; side buttons can sometimes be reserved for Back or Forward navigation.
Why are my mouse side buttons not detected?
Browsers or the operating system can reserve side buttons for navigation, and mouse software can remap them before the page sees the event. Test inside the focused area, check vendor mappings and compare another browser.
Can an online mouse tester diagnose a broken mouse?
It can confirm whether browser-visible clicks, movement and wheel events are arriving consistently, but it cannot inspect the physical switch or sensor directly. If the same failure appears across browsers and computers, hardware becomes more likely.
Why does a side mouse button not appear in the tester?
Some side buttons are reserved for browser Back/Forward actions or are remapped by mouse software, so the web page may not receive them as normal button events.
Does the mouse tester install a driver or record movement?
No. It listens to browser events only while the page is open and does not require a driver or upload your pointer movement.
How accurate is this mouse tool?
Some side buttons may be reserved by the operating system or browser and may not be exposed to web pages.
What should I do if the mouse result looks wrong?
Test another USB port, reconnect wireless receivers, check mouse software mappings and compare another browser. Side buttons can be reserved for Back/Forward navigation, so test them inside the focused surface.
