Decent, so far. TYSM for having this available!

Unfortunately it's a bit glitchy on Facebook IM, though (but so far perfectly OK on FB as a whole, Dark Mode or not). If you have Facebook's internally-built Dark Mode on as well as this extension on, the only way you can BARELY read your IM text is if you change the "theme" colour to a gradient (even then it is pretty hard to read).

Otherwise if your IM "theme" is anything else BESIDES a gradient, your background goes transparent and you can hardly read a thing that is written or outputted in the output window via the IM"s text field input, because all of the other text "underneath" shows plain through. So everything you type and see outputted, gets all garbled up in your output window, as well as your input text field.

Otherwise, looks great globally on other sites...like Google.ca (etc.), for now. Happy to keep you posted if any other glitches turn up. Thank you SO MUCH FOR HAVING THIS, btw! My existing on and off migraines will GRACIOUSLY appreciate this! <3 ,\m/

Looking forward to seeing the FB IM glitches fixed, soon.

Cheers and all of the best to everyone in the developing world out there!

Hope to be able to join you all some day, once I'm done with or able to take a significant break, from sewing masks.

The one they blocked was better and they should unblock it

This is real wonderful extensions. I love it

works like a charm

Makes some night mode websites, e.g. reddit, very bright

This is very nice extension, I am very very love it. Thank you so much, Bernard.

Just inverts all colors. Doesn't actually make everything dark. No option for whitelisting specific websites.

It's nice, I like the options we have and the ability to create custom themes, but I don't like the fact that it is automatically applied to every website. I wish there was an option for opt-in, you could enter the few sites you actually want to have dark mode on.

Piece of garbage doesn't work either phone, tablet or computer.

What about an option to force a website to use dark mode even if not set globally? A sort of opposite to the exclusion-of-some-sites option.

Very good extension, but I just came across a weird thing. I was viewing a local XML-page and these lines were added to the XML:

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.
