A middle mouse button not working comes down to one question: does the wheel click reach the computer at all? Press the wheel inside the middle click test. If the wheel lights up and the counter rises with each press, the button works and the fix is a setting in your mouse software, browser or app. If nothing lights up, the switch under the wheel is dirty, worn or remapped in the mouse's own software, and the hardware sections below apply. The test also shows a press that arrives twice, and a wheel that turns while you press it, which makes you scroll by accident.
Quick checks
- Press firmly in the middle of the wheel, straight down. Pressing near the front or back edge can tilt or turn the wheel instead.
- Try a different app. Middle click a link in your browser and click a tab with it. If it works in one place but not another, the app is the problem.
- Open your mouse software and look at what the wheel button is set to.
- Try the mouse on another computer. If the click is dead there too, the switch is at fault.
- On a laptop touchpad, check that a middle click is set up at all. Windows does not enable it by default.
Check the mouse software
Mouse apps can assign the wheel click to anything, or turn it off:
- Logi Options+ and Logitech G HUB: select the mouse, then the wheel button, and set it back to Middle click. On MX Master mice, the button behind the wheel switches the wheel between ratchet and free spin. The middle click is a press of the wheel itself.
- Razer Synapse, SteelSeries GG and Corsair iCUE: open the mouse's button assignments and set the wheel click to middle click.
- Profiles: many apps switch profiles per game or app. A profile that remaps the wheel can be active without you noticing. Reset the profile to default to test.
Also close remapping tools and scripts you may have installed, such as AutoHotkey scripts or mouse gesture apps. They can take the middle click for themselves.
Middle click not working in the browser
- Opening links in a new tab works in every major browser. If it does not, an extension or the page is catching the click. Test in a private window with extensions off.
- Autoscroll, the scroll icon that appears when you middle click an empty part of a page, works by default in Chrome and Edge on Windows. In Firefox, open Settings > General, scroll to Browsing and tick Use autoscrolling. Chrome and Safari on a Mac do not autoscroll.
- Closing a tab with a middle click on the tab works in Chrome, Edge and Firefox.
Middle click on a touchpad
Windows 11: open Settings > Bluetooth & devices > Touchpad > Three-finger gestures and set Taps to Middle mouse button. A three finger tap then sends a middle click.
Windows 10: open Settings > Devices > Touchpad, find Three-finger gestures and set Taps to Middle mouse button.
If those options are missing, the touchpad is not running as a precision touchpad, so install the touchpad driver from your laptop maker. To see the click arrive, use the touchpad test, which lights its middle click item when the gesture is set up.
Mac and Linux
- Mac: a standard mouse's middle button works on a Mac and opens links in new tabs. A Magic Mouse and Mac trackpads have no middle click without third party software. If a middle click opens Mission Control instead, open System Settings > Desktop & Dock, select Shortcuts and check the mouse shortcut menus for Mission Control, Application windows and Show Desktop.
- Linux: a middle click pastes the text you last selected, which surprises people coming from Windows. That is normal behavior, not a fault.
Apps that need a middle button
3D and design apps rely on the middle button to orbit or pan. Blender has an option for laptops and two button mice: open Edit > Preferences > Input and tick Emulate 3 Button Mouse, which lets Alt and the left button stand in for the middle button. Games let you bind actions to the middle button in their control settings, so check that the binding is still there after an update.
Reinstall the mouse driver
- Right-click Start and open Device Manager.
- Expand Mice and other pointing devices.
- Right-click each entry, choose Uninstall device, then restart.
Windows has no built-in setting to remap or disable the middle button, so if the click shows in the middle click test, Windows is passing it on.
Clean the switch under the wheel
The middle button is a small switch underneath the wheel's axle. Dust and fluff collect around the wheel and stop it from closing cleanly.
- Unplug the mouse or switch it off.
- Blow short bursts of compressed air into the gaps on both sides of the wheel while you press it down and turn it.
- Press the wheel 20 or 30 times, then test again.
A click that registers only when you press hard, or that sometimes arrives twice, is a worn switch. The double press is the same fault that makes buttons click twice, explained in mouse double clicking.
Use another button as a middle click
While you wait for a repair, or if you rarely use the side buttons, give the middle click to another button:
- Mouse software: in Logi Options+, G HUB, Razer Synapse and similar apps, set a side button to Middle click.
- Microsoft mice: Microsoft Mouse and Keyboard Center can reassign the buttons on supported Microsoft mice.
- Other mice on Windows: Windows itself cannot remap mouse buttons, so a free remapping tool is needed. Install only well known ones, since they see every click.
Then check the new assignment in the middle click test: the middle button should light when you press the side button.
When it is a hardware fault
If the middle click test stays dark on every computer after cleaning, the switch has failed. Inside the warranty, claim a replacement before opening the mouse. Out of warranty, the switch is usually a small tactile or micro switch soldered to the board under the wheel, and a matching part costs a few dollars. Open the mouse, note the switch's size and pin layout, desolder it, fit the new one, and test every button before you close the case. If scrolling also jumps or skips, that is a separate part, the wheel encoder: check it with the mouse wheel test. For the left, right and side buttons at the same time, use the mouse tester, and if the whole mouse has stopped, see mouse not working.
Middle click questions
Why is my middle mouse button not working?
Either the click never reaches the computer, because the switch under the wheel is dirty or worn or the mouse software has remapped it, or it arrives and an app or browser ignores it. The middle click test tells you which: if the wheel lights up there, the button works and the fix is a setting.
How do I middle click on a laptop touchpad?
On Windows 11, open Settings, Bluetooth & devices, Touchpad, Three-finger gestures and set Taps to Middle mouse button. Windows 10 has the same option under Settings, Devices, Touchpad. Then a three finger tap sends a middle click. A Mac trackpad has no middle click without extra software.
How do I turn on autoscroll with the middle mouse button?
In Firefox, open Settings, General, scroll to Browsing and tick Use autoscrolling. Chrome and Edge on Windows autoscroll by default when you middle click an empty part of a page. Chrome and Safari on a Mac do not autoscroll.
Why does middle click not open links in a new tab?
An extension that uses mouse gestures, or the site itself, can catch the middle click before the browser does. Try the link in a private window with extensions turned off. If it works there, turn the extensions back on one at a time. Also check that your mouse software sends a plain middle click.
Can I fix a broken middle mouse button myself?
Often. Blow compressed air into the gaps beside the wheel while you press it, which clears dust from the switch. If the click is still missing or unreliable, the small switch under the wheel can be replaced with a soldering iron for a few dollars, or the mouse claimed under warranty.
