until it gets an option to base the theme on dark background, it's useless. also, it keeps resetting my custom theme.

Beautiful

Excellent control over the theme.

The themes look great but there should be an option to change the new tab background. Also can you please give the option to download the theme directly to Firefox instead of applying it through the plugin?

Lately Firefox has not been restoring my colors when I restart, until I revisit color.firefox.com in a new tab.

It is mind blowing that your theme doesn't sync.

No way to change new tab page colour from white - Overrides dark theme and userContent.ccs so no workaround.
