why does it not working?!

Switch on each time on each site separately or make it automatic and then see awful invert of already dark by default pages. Not handy.

gray background with black text awesome

I had to downgrade to 0.4.5 because this version works much better for me, even though I have the latest version of Firefox. In 0.53 I had difficulties on Amazon, Wikimedia and DeepL. For example, the Wikimedia page was displayed brightly in 0.53, but this was not the case until 0.4.5. In version 0.4.5 everything works again for me as I am used to. I wonder for how long, because there are constant Firefox updates and at some point version 0.4.5 will stop working. If it is updated again to 0.53 I will try to install 0.4.5 again.

Recently it broke reCaptcha and cloudflare captcha check, makes absolutely no sense.

dark mode toolbar button cannot be found, will not sync across devices. big waste of time to try to find any information on how to make it sync or even how to make it appear on the toolbar. not consistent, thus useless.

DO NOT DOWNLOAD. FIND SOMETHING ELSE BY SOMEONE ELSE!!!!!!
Don't get it, it breaks most websites, there is no way to whitelist websites so it doesn't touch them, opening images in a new tab gets broken, key logging(beware), hasn't seen an update since it was released. Mozilla should just remove this add-on all together. developer is also inactive and does not give or provide support. DO NOT DOWNLOAD. FIND SOMETHING ELSE BY SOMEONE ELSE!!!!!!

Just recently, right-clicking on an image and "Open Image in New Tab" fails to open up an image. Turning off this extension solves this problem, so it's very likely Dark Mode.

Does not seem to work with Firefox. Youtube tutorial does not show how to enable on Firefox.

WARNING: Don't install this addon! In Firefox on Linux, it freezes the browser, consumes excessive RAM and makes the system crash.

rubbish

Extension causes product pages on Costco.com to freeze and use 100% CPU, disabling this extension fixes issue

Google home page is not dark. Even this page is not dark. Conversely, when you open those two pages on Chrome (with overriding dark theme flags on), this page is dark. This extension should be renamed Sometimes Dark Mode.

lächerlich, es inventiert nur die farben

Doesn't work when you need it.

Not working as of May 28 2021. I removed it because it's broken

Wenn eine Webseite Darkmodestyle bereitstellt, sollte der Style genommen werden und nix anderes!

No funciona.

It has conflict with some website even when it is not activated. Namely I can talk about element.io which gets smashed by this addon. Also, it prevents browserSync to work properly.

I couldn't find the source code of this add-on. I wonder if this violates the license itself.

Running Firefox on an iMac in dark mode itself. This extension doesn't provide dark mode for any pages within Firefox.
