override page colors button firefox 57+
https://support.mozilla.org/en-US/kb/change-fonts-and-colors-websites-use
I have pinned about:preferences#content to access Colors and switch between Always or Never but a toolbar button would be much better.
There are a few addons related to this like https://addons.mozilla.org/bg/firefox/addon/toggledocumentcolors-198916/ but after firefox 57 is released they would probably not work and most of them are too complicated.
Is it even possible to write a simple addon using web extensions for a toolbar button to simply switch between the colors defined in Prefences > Colors and the default web page colors?

yes i have looked at the available addons. this one appears to make background white and text black, it does not use the browser defined colors
I don't think that it is possible to use the settings as set via Options/Preferences because a You're WebExtension doesn't have access to prefs. You would have to modify the extension and have it signed on the Add-ons website under a different ID.

Maybe this extension works better:
Both extensions inject a CSS file on web pages, but have a different approach if you check their background.js file and their CSS file.
