Absolutely love this extension but, sadly, it has been slowing down my firefox considerably lately when using it. Probably going to have to look for something more lightweight to use more often.

Extensão muito boa tanto para o Firefox de Desktop e que pode ser instalada no Firefox Nightly para Android, funciona bem as funções de cores, mas precisa melhorar a resolução de tela da mesma quando executada no telefone.

Always get this message:

Today is my first day using this extension. Overall, I like it. I can tolerate that it's slower than Dark Reader, due to the fact its more customizable in my experience.

One issue I'm having is that some websites it wont remember when I apply "automatic" or "complex" filtering, etc, so the website looks as I would like it to. Is there a fix for that? Hitting "apply" doesn't make it stick, and I don't want it to become part of the default theme, as "automatic" runs best for most websites so far.

Hopefully in the future it runs better! No more white section on google images is definitely a win!! : )

Edit Sept 22, 2021; I see, Thank you! I'll see what I can do about the unnamed color scheme.

Not sure why, does NOT run well on Trello. Other websites, the delay is alright, but Trello locks up on me. Just be aware of that, other users, if you also need to use Trello. I still like the app, though.

4 stars for the response.

Just testing tons of dark mode type addons today to honestly just try to fix one single annoyance on one single site that has issues with a small on site popup that shows recent notifications. I have to admit that I don't really like messing with extra stuff if I don't have to either. However, this addon has fixed my annoying problem and worked well so far on a few quick test sites right out of the 'box'. I do have to say that I notice a whee slow down as people have mentioned about, but it's minimal (to me). So far this has been the first addon though to do all things dark just right where I need that, and also actually makes it super easy to whitelist/blacklist sites with a click. I'm still going to go searching for more tests with more addons, but so far this one gets everything right pretty much from my tests for this current version.

A great addon i've been using for ages now, but recently after turning it on/off for any website it'll throw up 'Midnight Lizard
Settings application failed. Refresh the page and try again.
QuotaExceededError: storage.sync API call exceeded its quota limitations' with no guide on what this is or how to fix. I removed all site settings to start fresh but still no ball.

Does the job well, but can massively slow down the browser.

Generally works well. Of course, there are cases when it hangs or makes a page unintelligible (for example, yandex.ru/search/?text=asdf shows a blank window). Fortunately there is an option to not apply to specific sites. Also the feature to resize/move the extension window is badly needed, to enjoy WYSIWYG effect). The manual would be handy.
