How to Fix Slow Scrolling in Chrome and Firefox

Scrolling through a webpage should feel smooth and responsive. But sometimes Chrome or Firefox starts scrolling slowly, stuttering, or lagging, especially on long or graphics-heavy websites.

The problem can be confusing because your mouse may work normally in other applications while scrolling feels noticeably slower inside the browser.

In most cases, you don’t need to reinstall Windows or replace your mouse. The cause can be something as simple as a browser extension, hardware acceleration, graphics drivers, mouse settings, or a webpage that is using too many system resources.

This guide explains how to troubleshoot slow scrolling in Chrome and Firefox without making unnecessary changes to your system.

First, Find Out Where the Problem Is

Before changing browser settings, perform this simple test.

Open another application, such as File Explorer, and scroll through a folder.

Then compare it with scrolling in Chrome or Firefox.

If scrolling is slow everywhere

The problem may be related to:

• Your mouse or touchpad
• Windows mouse settings
• USB or Bluetooth connection
• Graphics drivers
• System performance

If scrolling is slow only in Chrome or Firefox

The problem is more likely related to:

• Browser extensions
• Hardware acceleration
• Browser settings
• A specific webpage
• Browser profile or temporary data

This distinction can save you from changing settings that have nothing to do with the actual problem.

1. Test a Different Website

Before changing anything, open several different websites.

For example, test:

• A simple webpage with mostly text
• A website with images and videos
• A long webpage where you normally notice the problem

If scrolling is smooth on simple websites but becomes slow on a particular site, your computer may not be the problem.

Some websites use heavy animations, advertisements, videos, or scripts that can increase CPU and GPU usage while scrolling.

If the problem occurs on almost every website, continue with the next steps.

2. Check Chrome or Firefox in a Private Window

Browser extensions can interfere with webpages and sometimes cause scrolling performance problems.

This is one of the quickest ways to test for an extension-related issue.

Google Chrome

Open an Incognito window by pressing:

Ctrl + Shift + N

Visit a website where scrolling normally feels slow.

Mozilla Firefox

Open a Private Window by pressing:

Ctrl + Shift + P

Then test the same website.

What the Result Means

If scrolling becomes smooth in the private window, an extension or browser-related setting is a strong suspect.

Disable extensions temporarily and test them one at a time.

Chrome

Type:

chrome://extensions

into the address bar and press Enter.

Disable your extensions one by one.

Firefox

Type:

about:addons

into the address bar and press Enter.

Disable extensions individually and test scrolling after each change.

Pay particular attention to extensions that modify webpages, block content, inject scripts, or constantly monitor page activity.

3. Check Hardware Acceleration

Hardware acceleration allows the browser to use your GPU for certain graphics-related tasks.

It can improve performance, but an incompatible graphics driver or GPU configuration can sometimes produce the opposite result, including stuttering or scrolling problems.

Google Chrome

1. Open Chrome.
2. Click the three dots in the top-right corner.
3. Select Settings.
4. Open System.
5. Find Use graphics acceleration when available.
6. Toggle the setting.
7. Click Relaunch when Chrome asks you to restart.

Test scrolling again.

If the problem becomes worse after changing the setting, return it to its previous state.

Mozilla Firefox

1. Open Firefox.
2. Click the menu button.
3. Select Settings.
4. Stay in the General section.
5. Scroll down to Performance.
6. Disable Use recommended performance settings.
7. Check or uncheck Use hardware acceleration when available.
8. Restart Firefox.

Test scrolling after restarting the browser.

Important: Hardware acceleration is not automatically bad. If disabling it makes scrolling worse, turn it back on.

4. Update Your Graphics Driver

If scrolling became slow after a Windows, browser, or graphics-related update, your GPU driver may be worth checking.

This is especially relevant if you notice:

• Scrolling stutters
• Video playback problems
• Flickering
• Browser animations becoming choppy
• High GPU usage
• Problems across multiple browsers

Open Device Manager:

1. Right-click the Start button.
2. Select Device Manager.
3. Expand Display adapters.
4. Identify your graphics card.
5. Check for an available driver update.

For the most reliable driver, you can also check the official support website for your graphics hardware manufacturer.

Common manufacturers include Intel, AMD, and NVIDIA.

Avoid random third-party driver websites.

5. Check Windows Mouse Settings

Sometimes the browser is not actually scrolling slowly. Windows may simply be configured to move fewer lines with each mouse-wheel step.

Open:

Settings > Bluetooth & devices > Mouse

Look for the mouse wheel settings and check the number of lines Windows scrolls each time you move the wheel.

If it is set unusually low, increase it and test again.

Don’t assume that a higher value is automatically better. Choose a setting that feels comfortable and responsive with your mouse.

6. Check Whether Your Mouse Is the Problem

If scrolling is slow or inconsistent in multiple applications, test another mouse.

For a USB mouse:

• Try another USB port.
• Avoid testing through a faulty USB hub.
• Check whether the cable is damaged.

For a wireless mouse:

• Replace or recharge the battery.
• Move the receiver closer to the mouse if possible.
• Try another USB port for the receiver.
• Temporarily disconnect other wireless devices if you suspect interference.

If another mouse scrolls normally, the original mouse is likely the source of the problem.

7. Check CPU and Memory Usage

A browser may become sluggish when the system is under heavy load.

Press:

Ctrl + Shift + Esc

to open Task Manager.

Check:

• CPU usage
• Memory usage
• GPU usage
• Disk usage

Then look at which applications are consuming the most resources.

If CPU or memory usage is extremely high, close unnecessary applications and browser tabs before testing again.

A browser with dozens of open tabs can consume a surprising amount of memory, particularly when several websites contain video, animations, or interactive content.

8. Check Chrome’s Task Manager

Chrome has its own task manager, which can help identify a problematic tab or extension.

Press:

Shift + Esc

inside Chrome.

You’ll see information about Chrome processes, including:

• Tabs
• Extensions
• CPU usage
• Memory usage
• GPU processes

If one tab or extension is consuming significantly more resources than the others, close it temporarily and check whether scrolling improves.

This is much more useful than blindly disabling random browser settings.

9. Try Firefox Troubleshoot Mode

Firefox provides a built-in troubleshooting mode that temporarily disables extensions and some custom settings.

To use it:

1. Open Firefox.
2. Click the menu button.
3. Select Help.
4. Choose Troubleshoot Mode.
5. Restart Firefox when prompted.

Then test scrolling.

If the problem disappears in Troubleshoot Mode, an extension, theme, or customization is likely involved.

If scrolling remains slow, continue troubleshooting the system or graphics configuration.

10. Clear Browser Cache

Clearing cached data can help with certain browser problems, particularly when a website behaves strangely after an update.

However, cache clearing should not be treated as a universal solution for scrolling problems.

Chrome

Press:

Ctrl + Shift + Delete

Select the appropriate time range and clear Cached images and files.

Firefox

Press:

Ctrl + Shift + Delete

Select the relevant time range and clear the Cache.

Then restart the browser and test the affected websites again.

Your browser cache is designed to improve performance, so clearing it is not something you need to do regularly just because a webpage scrolls slowly.

11. Check Chrome and Firefox for Updates

An outdated browser can contain bugs that have already been fixed in a newer release.

Chrome

Open:

Menu > Help > About Google Chrome

Chrome will automatically check for available updates.

Firefox

Open:

Menu > Help > About Firefox

Firefox will check for updates and install them when available.

Restart the browser after updating and test scrolling again.

12. Check Windows Updates

If both Chrome and Firefox are experiencing scrolling problems, Windows itself may be involved.

Go to:

Settings > Windows Update

Check for available updates and install pending updates if appropriate.

If the issue started immediately after a Windows or graphics driver update, note when it happened. That information can help identify whether a recent software change caused the problem.

13. Disable Unnecessary Extensions

If you discovered that scrolling is smooth in Incognito or Private mode, don’t immediately reinstall the browser.

Instead, disable extensions individually.

Common examples include:

• Ad blockers
• Grammar checkers
• Shopping extensions
• Page customization tools
• Screenshot tools
• Video enhancement extensions
• Script or content modification extensions

After disabling each extension, reload the affected webpage and test scrolling.

Once you identify the problematic extension, update it or remove it.

14. Check if the Problem Happens in Another Browser

This is another valuable diagnostic test.

If scrolling is slow in Chrome but perfectly smooth in Firefox, the issue is probably related to Chrome rather than your mouse or Windows system.

If Firefox and Chrome both have the same problem, investigate:

• Windows mouse settings
• Mouse hardware
• Graphics drivers
• CPU and memory usage
• Windows updates
• System performance

This test helps narrow down the source without making unnecessary changes.

15. Reset Browser Settings as a Last Resort

If the problem affects only one browser and the previous troubleshooting steps have failed, resetting the browser can be worth considering.

Before doing this, make sure your important browser data is synchronized or backed up.

A reset can remove or restore various customized settings, so don’t use it as your first troubleshooting step.

Start with extensions, hardware acceleration, updates, and performance checks first.

What If Scrolling Is Slow Only on One Website?

If Chrome and Firefox both scroll smoothly everywhere else but one website is slow, the problem may be with that particular website.

Possible causes include:

• Heavy animations
• Video backgrounds
• Large advertisements
• Excessive JavaScript
• Poorly optimized page elements
• Very large images
• Browser compatibility issues

Try opening the same page in another browser.

If it remains slow in both browsers, your computer may not be the cause at all.

When Should You Suspect a Hardware Problem?

Hardware becomes more likely if scrolling is slow across multiple browsers and applications.

Look for other symptoms such as:

• Mouse movement feels delayed
• Video playback stutters
• The entire desktop feels sluggish
• Graphics applications perform poorly
• The computer frequently freezes
• CPU or GPU temperatures are unusually high

If the problem affects the entire system rather than just the browser, investigate the mouse, graphics driver, system performance, and hardware health before focusing exclusively on Chrome or Firefox.

Frequently Asked Questions

Final Thoughts

If Chrome or Firefox is scrolling extremely slowly, don’t immediately assume that your computer needs a major repair.

Start by determining whether the problem affects one website, one browser, or the entire system. Then test private browsing mode, disable extensions, check hardware acceleration, and verify your Windows mouse settings.

If both browsers are affected, look beyond the browser itself. Check your mouse, graphics driver, CPU and memory usage, and Windows updates.

The most important step is identifying where the problem actually starts. Once you know whether it’s the website, browser, mouse, or Windows, the solution becomes much easier to find.
