User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0

Steps to reproduce:

Opened about:config
Modified browser.display.background_color value to #ADADAD

Actual results:

Blank pages remain WHITE.

Expected results:

Blank pages should have turned GREY or what ever the modified value is set to. The browser.display.background_color stopped working in version 94. This feature worked in the previous desktop version.

I ran into the same issue. I opened up about:preferences and clicked the Colors… button. Then I unchecked "Use system colors" which had been enabled after the update for whatever reason.

Can confirm. Disabling "Use system colors" under the about:preferences > Colors fixed this issue.

The Bugbug bot thinks this bug should belong to the 'Core::Graphics' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

This was an intentional change from bug 1593273. Maybe in hindsight we could've made a migration to keep the old default for users with customized browser.display.* prefs or something.

Set release status flags based on info from the regressing bug 1593273

Too late to build a migration path now.
