Default theme does not work in MacOS dark mode

[atishay]

I switch to the MacOs dark mode based on the time of the day. The default theme in Firefox does the same. But the rounded corners theme change only works in one mode. Need a way to run this correctly in both light and dark modes of MacOS

Hi there, currently the project does not support automatically switching to different colours, I might support it one day but I need to get my hands on OSX Mojave first, as this Firefox feature is not available in Sierra.

@wilfredwee If you can help me identify the firefox css classes which identify the dark vs light mode, I might be able to help with a pull request.
