Did anyone actually test how fast it is compared to Dark Reader?
Calling yourself "the fastest" is all nice and good, but some benchmarks would be nice.
- Yep, people have benchmarked:
  Firefox without any Dark Mode addon = 27 points Speedometer
  With Dark Reader = about 11 points
  With UltimaDark = 25-26 points
- Try it your self. Use a pretty low end device. You will see difference. It's life saver for my eyes and pretty old computer.
  
  My "pretty low end device" is an Android, which they do not support. :/

Ah it doesn't work on Android? A pity, that's where I need dark mode the most.
- Dark Reader works a charm on Android.
- It works but it's config interface looks borked
  Edit: NVM, it also breaks some sites
- I just tried it on a Firefox fork and it works fine.
  Just go to the link in OP, then enable Desktop Mode in Firefox. That will let you install it.
- Didn't tried on android.

Pro tip: Firefox can do dark mode natively, if you're ready to accept some ugly websites.
Settings > Manage colors > then set your preferred hues and Override to Always.
It's blazing fast with zero white flash, and most sites are perfectly legible.
- While I'm glad they're trying this, it has the same problem as Brave, no configuration. Dark Reader lets you configure individual site profiles via a toggle of static/dynamic/etc to fix ones that don't work well. Without that, nothing will compare.
- Is there a way for the same on Firefox on Android, Fenix?

Although it works well, this is so experimental, it makes lab rats look like seasoned professionals.
Looks good, but I wait until its proven and stable.
- It's been in development for 4 years.
  
  That doesn't mean it's stable. From his own description:
  This is still highly experimental so it can also ruin your internet experience
  
  Because of the fact that UltimaDark is going the hardest route, using a totally different API, unlike Dark Reader

Dark Reader has been in development since 2014 and is much more polished

Unfortunately, it is not available on #Firefox mobile.

On my rather old FP3 it spares me a few seconds per page load and the result seems quite comparable to dark reader.

Dark Reader is intensive, I will give this a shot. So far so good on FF mobile.
- Yea, It uses native features of Gecko engines that's why it's faster than Dark Reader.
- How did you install it on mobile? Do you need to use the nightly?
  
  Nope, you can install extensions to regular FF for a while on Android. Go to addons.mozilla.org and install like how you would do it on desktop. Request desktop site if extension claims to be incompatible.

Maybe I'm an idiot, but I can't find a source link. Is this open source? I was curious about finding information comparing it to darkreader

thanks for the suggestion

Anyone tried this with twitch? I just get a gray screen instead of video. Anyone else? Really like this extension otherwise
- Twitch already has a dark mode available in the settings.
  
  The issue is more that the extension doesn't seem to properly let sites bypass or something. I have to turn the extension off and refresh to get picture back.

yoo this works with resist fingerprinting

Don't use dark mode as it is bad for privacy
- How so?
  
  Websites can look at their own structure, and they can see the changes addons make to them, for example of a CSS property was changed or added.
  Maybe there are ways around that, like with the use of a shadow DOM, but I'm not a web developer
- What?
  
  It makes you unique from a fingerprinting perspective.
