In Pale Moon, setting a page background color doesn't seem to work. Oddly, the checkerboard option does work, but setting a custom color does not. Could you please update this extension to fix this problem?

EDIT: Wow, I was not expecting a response so quickly, let alone a workaround for the problem I was having. Thank you so much!

This review is for a previous version of the add-on (3.0.4.1-signed.1-signed). 

Workaround: append !important (e.g. "white !important").

I'm not sure if I can safely make ODIS set !important on all backgrounds though (and even if I did that, the default would still be Pale Moon's #2e3b41 rather than white).

The alternative is to use Pale Moon's own custom background color setting (browser.display.standalone_images.background_color, which you can set from about:config).
