Usually a hardware, browser, or accessibility issue — here’s what’s causing it and how to stop it
Facebook scrolling on its own — moving up or down without you touching anything — is disorienting and makes the platform nearly unusable.
The cause is almost never Facebook itself. Auto-scrolling is almost always a hardware input issue, a browser setting, a stuck key or mouse button, or an accessibility feature that’s been activated. Here’s how to identify what’s driving it and stop it.
A Stuck or Dirty Mouse Wheel
This is the most common cause of automatic scrolling — not just on Facebook but across all websites. A mouse wheel that’s slightly stuck, dirty, or mechanically worn can send continuous scroll signals to the browser even when you’re not touching it.
Test by unplugging your mouse and seeing if the auto-scrolling stops. If it does, the mouse is the problem.
Clean the scroll wheel by rolling it rapidly back and forth several times — this can dislodge dust and debris that’s causing it to register false inputs. A can of compressed air blown around the wheel clears more stubborn debris.
If cleaning doesn’t help, test with a different mouse. If a second mouse doesn’t cause auto-scrolling, the original mouse’s scroll wheel has worn out mechanically and needs to be replaced.
Middle Mouse Button Auto-Scroll Mode
Clicking the middle mouse button — the scroll wheel button — activates auto-scroll mode in most browsers. In this mode the browser scrolls automatically in whatever direction you move the mouse, and scrolling continues until you click the middle button again to deactivate it.
If auto-scroll mode was accidentally activated, click the middle mouse button once to toggle it off. You’ll notice the cursor icon changes when auto-scroll mode is active — it shows a circular icon with arrows rather than the standard pointer.
This is one of the most commonly triggered accidental scroll behaviors because clicking the scroll wheel is easy to do without realizing it.
A Stuck Keyboard Key
The Page Down, Space bar, or arrow keys held in a pressed position cause continuous scrolling in browsers. If any of these keys are physically stuck — pressed down slightly, jammed by debris, or mechanically failing — they send a continuous scroll signal to the browser.
Press each of these keys deliberately several times to see if any feel sticky or don’t spring back fully. Also check whether anything is resting on your keyboard — a book, a bag, a phone — that might be pressing a key down continuously.
Disconnect your keyboard temporarily and see if the auto-scrolling stops. If it does, a stuck key is the cause. Clean around the stuck key with compressed air or carefully remove the keycap to clean beneath it.
A Connected Game Controller or Input Device
Game controllers, joysticks, and other USB input devices can cause scrolling behavior when connected to a computer. An analog stick that’s slightly off-center, a trigger that’s partially pressed, or a button that’s stuck can all send scroll commands to the active browser window.
Disconnect any game controllers, joysticks, drawing tablets, or other USB input devices and see if the scrolling stops. If it does, the input device needs to be recalibrated or checked for stuck controls.
Browser Smooth Scrolling or Extension Behavior
Some browser extensions — particularly those that modify scrolling behavior, add smooth scrolling effects, or implement infinite scroll features — can interact with Facebook’s own infinite scroll in ways that produce unintended continuous scrolling.
Test by opening Facebook in incognito or private mode where most extensions are disabled. If the auto-scrolling stops in incognito, an extension is causing it in your regular window.
Go to your browser’s extensions page and disable them one at a time, testing Facebook after each. Scroll-related extensions, page enhancers, and accessibility tools are the most likely culprits.
Facebook’s Infinite Scroll and Autoplay
Facebook’s feed is designed to scroll infinitely — it loads new content as you reach the bottom and keeps the feed moving. Combined with autoplay videos that shift content as they expand or collapse, the feed can appear to jump or scroll on its own even without a hardware input problem.
This is distinct from true auto-scrolling — the page is responding to content loading and video state changes rather than a continuous scroll signal. If the movement is in short jumps when content loads rather than smooth continuous scrolling, this is Facebook’s normal behavior rather than a malfunction.
Pausing autoplay videos reduces this. Go to Facebook Settings → Videos and set Auto-Play Videos to Off. This stops videos from expanding automatically and shifting the feed position.
Accessibility Settings — Automatic Scrolling Features
Windows and some browsers include accessibility features that enable automatic scrolling for users who have difficulty using a mouse or keyboard continuously. If any of these were accidentally enabled they can cause pages including Facebook to scroll on their own.
On Windows, go to Settings → Accessibility → Mouse and check whether Mouse Keys or any automatic scrolling features are enabled. Turn off anything that looks like it could produce continuous scroll input.
In Chrome, go to Settings → Accessibility and review any accessibility features that are active. In Edge, check Settings → Accessibility similarly.
Touchpad Gestures Triggering Scroll
On laptops, touchpad gesture settings can cause scrolling if the palm rejection isn’t working well, if a gesture is being triggered accidentally, or if something is lightly resting on the touchpad surface.
Check whether anything is touching or resting near the touchpad. A shirt cuff, a cable, or even a hand resting too close can register as a scroll gesture on sensitive touchpads.
Go to your touchpad settings — on Windows, Settings → Bluetooth and Devices → Touchpad — and check the scroll and zoom gesture settings. Reducing touchpad sensitivity or adjusting gesture thresholds can prevent accidental scroll inputs.
On laptops where this is a recurring issue, pressing the touchpad disable key — usually Fn + F7 or similar depending on the manufacturer — temporarily disables the touchpad to confirm whether it’s the source.
A Browser or System Update Changed Scroll Behavior
Occasionally a browser update changes how scrolling is handled — particularly smooth scrolling behavior — in ways that interact unexpectedly with Facebook’s infinite scroll implementation. If the auto-scrolling started immediately after a browser update, this is worth investigating.
Go to your browser’s flags or settings and look for smooth scrolling options. In Chrome, type chrome://flags and search for Smooth Scrolling. Try toggling it off and testing Facebook. In Edge, the equivalent is edge://flags and the same search.
Check for Malware
Malware that controls browser behavior can cause unexpected scrolling — particularly if the scrolling takes you to specific content, ads, or links rather than just moving the page randomly. Random auto-scrolling that pauses on ads or sponsored content is a specific pattern associated with browser hijacking.
Run a scan with Microsoft Defender or Malwarebytes to check for any browser-modifying malware. Browser extensions that were installed without your awareness are the most common vector — check your extensions list carefully for anything you don’t recognize.
A Quick Checklist
Work through these based on where you think the cause might be:
- Unplug your mouse and test — if scrolling stops, the mouse is the problem
- Click the middle mouse button once to deactivate auto-scroll mode if it was triggered
- Check for stuck keyboard keys — Page Down, Space bar, arrow keys
- Disconnect game controllers and other USB input devices
- Test in incognito mode to rule out extension interference
- Disable extensions one at a time to find the culprit
- Turn off video autoplay in Facebook Settings → Videos
- Check Windows Accessibility settings for any auto-scroll features
- Check touchpad settings on laptops for gesture sensitivity
- Check browser flags for smooth scrolling settings
- Run a malware scan if scrolling appears targeted at specific content
The Bottom Line
Facebook auto-scrolling is almost always a hardware input issue — a dirty or worn mouse wheel, an accidentally activated middle-click auto-scroll mode, or a stuck keyboard key — rather than anything wrong with Facebook or your browser. Unplugging the mouse and testing takes ten seconds and immediately confirms or rules out the most common cause.
If hardware isn’t the issue, the incognito test identifies extension interference quickly. Between those two tests, the cause is identified in under two minutes in most cases.
Facebook isn’t scrolling itself — something is sending it a scroll signal. Find the source of the signal and the scrolling stops.
