How To Enable Hardware Acceleration In Firefox 57 And Improve Performance

Firefox Quantum has addressed many performance issues that were present in the earlier versions. Unfortunately, Firefox 57 (Quantum) has been problematic for some and doesn’t offer the performance it claims in some cases. I’m referring to the responsiveness of the browser such as switching between tabs – I’ve also fixed tearing when scrolling by enabling hardware acceleration which could be useful for those who suffer from tearing in some Linux desktop environments. If you are using an older version of Firefox (eg: ESR, 56, 55) or Waterfox, this tweak can be applied for them too.

Disclaimer: Forcing hardware-acceleration on in Firefox could cause stability issues. If anything does go wrong, be sure to change the value to false.


  1. Open up a new tab in Firefox and type about:configin your address bar.
  2. A warning will popup – proceed by clicking “I accept the risk!”
  3. Paste the following into the search field layers.acceleration.force-enabled
  4. Double click on it to change it’s value to true. The text in that line should now be bolded.
  5. Restart your browser.
