I need to deploy the newest version of Mozilla Firefox ESR to my enterprise in the next couple weeks. It has been requested that I disable "Use Hardware Acceleration when available". I have been unable to find the setting name to disable in the mozilla.cfg file that configures the application during the install. Could you please tell me how I can uncheck this setting when deploying the current ESR version?

Hi

The two settings that I believe you may need to add to the mozilla.cfg file are;

lockPref ("gfx.direct2d.disabled", true); lockPref ("layers.acceleration.disabled", true);

I used lockPref based on this article.

(Please test and make sure before deployment.)

I hope this helps, but if not, please come back here and we can look into a different solution for you.
