Works sometimes good, but there are several times that I have to hack it up cuz it put Heavy Gray on Black

This add-on is very good to use with Tor Browser. I love this. Also, in some websites home page doesn't take take the dark effect but the sub pages takes the dark effect. I changed the setting from Dynamic to Static or Filter or Filter+ and it works fine.

YouTube video doesn't show instead it shows up black screen hence I have to whitelist YouTube from using this add-on. YouTube audio works.

Best night-mode extension possible!!

Must have app. There was a bug after an update and the developer fixed it within a day. Great app and responsive developer.

Optimo

It's possible to use a 'light' mode and force the font to change on any website! Unprecedented for any Dark Mode extension!

I am a fan of dark themes and this was a favor in my eyes, thank you very much!

Works well and is easy to use.

Really well-designed extension. As a developer who is building an extension, this level of usefulness and polish is what I aspire to.

A couple of small quibbles... it doesn't work on Google Maps--causes the site to seize up, probably because it is converting all the colors... also doesn't work very well on certain other sites; for example, if you are trying to view some color-coded information on wikipedia (https://en.wikipedia.org/wiki/Lewis_Hamilton#Complete_Formula_One_results) the colors don't translate so well... silver and grey are almost the same color. Sites that have their own built-in dark mode also render a bit screwy; ex: https://material-ui.com/api/modal/ . The built-in dark mode for most websites is better than the Dark Reader version for that site, which is to be expected.

But these are all really small quibbles... overall the app works really well, it's a joy to use, the ui is crisp and fresh. Really nice extension.

Not only substantially slows down my Firefox, but frequently causes most pages, particularly Nazibook, to stop responding

It work magnificently and you just have to try google map with this thing turned on =D

Tout bonnement excellent

Perfect
