Since July 6 or so it has become unusable. Over the course of 15 to 30 minutes the browser becomes so unresponsive that I have to close it. Disabling Dark Reader fixes the problem. I've tried refreshing firefox and reinstalling each addon one by one and only Dark Reader creates the problem. I've used it for, probably, over a year without any problems until the last few days. Web pages with videos on them seem to slow the most but eventually the browser becomes almost totally unresponsive over time regardless of the web pages.

I still give it 5 stars because I assume it will either be fixed or it's a unique problem that I'm having.

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

I used to mess around with addons like Stylize and such, but they worked very poorly. This addon is AMAZING!
