Try these fixes:

  1. Clear your history in Firefox
  2. Update to the latest version
  3. Disable Add-ons
  4. Turn off hardware acceleration
  5. Update your graphics drivers

Fix 1: Clear your history in Firefox

Firefox restores lots of information including the sites you’ve visited, files you’ve downloaded, and more. But there’re situations when problems like freezing emerge. So it’s always a good idea to clear the browsing history, cookies, and cache on a regular basis.

Here’s how you can do it:

1) In the upper right corner, click on the menu button (three lines).
Then select Library from the drop-down menu.

Fix 2: Update to the latest version

The latest Firefox version may substantially fix some bugs and improve the performance. So for the Firefox freezing issue, updating Firefox to the latest release might work.

By default, Firefox updates automatically. But you can always update it manually in case an update is downloaded but not installed. Here’s how you can do it:

1) In the upper right corner, click on the menu button (three lines).
Then select Help.

update Firefox

2) Click About Firefox.

3) Till then, the About Mozilla Firefox window opens and Firefox will check for updates and download them automatically. Once the download is complete, click Restart to update Firefox.

After restarting Firefox, check if it’s functioning normally. If it still freezes, move on to the next fix.


Fix 3: Disable Add-ons

An incompatible or outdated extension may freeze Firefox. So to get rid of freezes, you should disable them manually.

1) In the upper right corner, click on the menu button (three lines).
Then select Add-ons.

2) When the tab opens, head to the Enabled section and make sure the extensions you’ve enabled are switched to OFF.

After applying the changes, restart Firefox and check if this fixed the issue.


Fix 4: Turn off hardware acceleration

Hardware acceleration is a setting that allows Firefox to use your computer’s graphics processor to display graphics-heavy web contents. It’s turned on by default. But many users have reported that turning off hardware acceleration helps fix the freezing issue. So here, you can give it a shot.

1) In the upper right corner, click on the menu button (three lines).
Then select Options.

2) Under the General tab, scroll down and find the Performance section. Uncheck the box Use recommended performance settings in order to show the hardware acceleration option.

If turning off hardware acceleration really works, you’re recommended to update your graphics drivers to prevent more freezes in the future.


Fix 5: Update your graphics drivers

Driver updates provide bug fixes and compatibility with the software programs you’re running. So it’s highly recommended to update your graphics drivers on a regular basis to gain better performance on your PC.

There are two ways you can update your graphics drivers:

Option 1 – Manually – You’ll need some computer skills and patience to update your drivers this way because you need to find exactly the right the driver online, download it and install it step by step.

OR

Option 2 – Automatically (Recommended) – This is the quickest and easiest option. It’s all done with just a couple of mouse clicks – easy even if you’re a computer newbie.  

Option 1 – Download and install the drivers manually

NVIDIA and AMD keep updating drivers. To get them, you need to go to the official websites, find the correct drivers, and download them manually.

Once you’ve downloaded the drivers, double-click on the downloaded file and follow the on-screen instructions to install the drivers.

Option 2 – Automatically update your drivers

If you don’t have the time, patience, or computer skills to update the drivers manually, you can do it automatically with Driver Easy.
