Updated to 5 stars on account of me being dumb. Great work, Alex :)

I had found that there are sometimes issues with some random websites not loading / rendering correctly with Dark Reader enabled.

This is to be expected, since the way sites are coded & styled varies, sometimes a lot.

Fortunately, this extension DOES give you a user interface for dealing with such situations.

Hit the 3-dot button to display the general Firefox menu, and then scroll down to the Dark Reader option to access this extension's nicely built UI.

This allows you to disable the extension on a site-by-site / per-URL basis, making it the perfect companion for anybody with sensitive eyes.

Will NEVER EVER use any browser without this addon

Turning on this extension will slow the loading of web pages very much. I'd rather have my eyes hurt.

This started out great but over time has become and increasing nuisance. It really would be best if it had some sort of machine learning in it that allowed intelligent display of a page based on the page's settings, not necessarily this app. Renders Ecosia searches illegible and frequently makes pages look dusty rather than making them more readable; dark grey text on a taupe background is actually really difficult to read. It also eats up memory like nobody's business. Won't be using again, i'll just turn down the whole screen brightness and deal with it.

Memory leak time after time, can reach up to 10+gb and create a terrible experience...

Awesome! Very helpful extension for my eyes health!

Bilgisayarda kullandığım bu müthiş eklenti Firefox previewla birlikte androide de geldi. Üstelik android 10la gelen koyu/gece modunu otomatik algılayıp ona göre otomatik açılıp kapanıyor kesinlikle yüklenmesi gereken eklentilerden. Gece modu olmayan siteleri bile gece moduna sokuyor.

It was working fine for 3 weeks. Then it kept causing firefox to slow down and crash. Worked great otherwise, please fix this issue.

Can I have the old version back ?
this new update (on july 6, 2020) is a lot slower and make text selection impossible on some pages, as it makes the highligh selection to show only after 2 to 3 seconds
--- update ---
Finally, after testing all combinations, it seems that it is a Firefox issue more than coming from this extention. I uninstalled all plugins/extensions and I still had the issue.
But it doesn't explain why it was working a day before while this was the only extension that had an update on the 7th of july.
Also, it doesn't explain why the "Owl" extension solves the issue when activated.

Perfect add-on. Now fast enough for daily usage

Good ADD-ONS
