Click on the Settings gear in a new Mozilla tab. (⚙) Then, click on the "Manage more settings" option. Then, in the left down corner, you will find the "Extensions & Themes". Clicking on that will take you to Add-ons page. "about:addons" Select your prefered theme. "LIGHT" theme makes it back to a white background.
