This is one of the most useful addons for Firefox!

Still, without any attempt to decry Bernard's good work, I do need to say it's a pity that addons like these are necessary at all, because web page designers do not think of any thing else besides shiny white pages with black writings. This might look good when you're sitting inside a well illuminated office, but that's not where everyone else is reading their pages.

My chat window on facebook looks little weird, becase it makes the window black on elliptical area, the rest is still white.

Very helpful extension, thanks! | Очень полезное расширение, спасибо!

This extension makes up for all the web apps out there that refuse to give their users a dark mode. Works great with Freshdesk!

It works perfectly

Thanks u so much :D !!!!!!!!!!!!!!!
