Hello,

I am using windows 11 in darkmode and firefox is also set to open in dark mode.

While I am opening firefox, white flashing window is appearing for 1-2 seconds and then opening a darkmode firefox.

Why there are white flashes in darkmode? Can anyone please provide a resolution.

Thank you.

There are a few things you can try.

1. In about:config change the colour in browser.display.background_color If you use black, that will interfere with how websites are displayed so I suggest an off-white colour. I use a light variant of Tan.

2. Use a User-script such as No Brighter. You will have to install a script manager such as Greasemonkey.

3. Code in userChrome.css which you have to create yourself; more if you wish.
