  1. Disable Antivirus and Firewall temporarily.
  2. Disable any recently installed extensions.
  3. Disable Hardware Acceleration.
  4. Run Firefox in Troubleshoot mode.
  5. Update Display Drivers.

Why does Firefox turn black?

The Black screen issue in Firefox occurs mainly due to a new feature called Off Main Thread Compositing (OMTC) which causes updates, animations and videos to pause. To fix it follow any one of the following methods and see if it fixes your problem.

1] Disable Antivirus and Firewall temporarily

Anti-virus programs are built to monitors the behavior of programs thoroughly and report any suspicious activity, if detected. This vigilance at times can become a nightmare; if the software blocks your WiFi or stops you from connecting to a website. Then, it becomes essential to disable Antivirus temporarily. Here’s how you can disable Windows Defender in Windows 11/10.

2] Disable any recently installed extensions

Browsers like Chrome, Firefox and others allow customization on your desktop by adding extensions but at times, their installation results in unwanted problems. So, if you find the Firefox screen has gone black after the installation of an extension, remove the extension or disable it temporarily.

3] Disable Hardware Acceleration

Disable Hardware Acceleration

Though Hardware Acceleration improves the performance of an application significantly, it can have an adverse effect sometimes, if not configured properly. Turning off the Hardware Acceleration completely will run the application in software rendering mode but if it solves your issue, go ahead and disable it.

4] Run Firefox in Troubleshoot mode

Firefox Troubleshoot Mode

This is a special mode in the Firefox browser that can be used to diagnose and fix problems. When enabled, it temporarily disables add-ons (extensions and themes), turns off hardware acceleration and certain other features, and ignores some customizations (see below to learn more). So, by comparing Firefox’s behavior in normal mode to its behavior in Troubleshoot Mode you can pinpoint the cause of the problem and fix it. Troubleshoot Mode was known as Safe Mode in previous versions of Firefox.

5] Update Display Drivers

Update your Display Drivers and see if that helps you.

Hope this helps.
