should be able to manage through extensions manager or opening the extension page from it. I'd like to remove the icon from the bar, but it is THE way to manage the extension, so whenever i need to change any settings, i've got to add it back to the bar manage and remove it which is really annoying. Still, working good, hence the stars

Good but doesn't work on all sites.

Looks great, but it causes frequent slowdown and hesitation on web pages. I know this extension is the problem because when I disable it, the issues go away. I prefer the "Dark Background and Light Text" extension.

Slowed down the performance in certain sites which translated into sites not loading completely. Good overall but heavy on resources.

Very useful extension, but uses too much resource which leads Firefox to be irresponsible in "not too simple" websites.

Why it's so slow? Significantly slowing down using Firefox at all! Much slower than other dark mode addons, why? Please fix it otherwise it is not useful even when the quality of websites looks great.

这个功能很棒，深色系确实很舒服。但是问题是，网页加载的一瞬间还是有白屏闪现，就像CSGO丢了个高闪一样让人无语！！！....

Awesome extension. Doesn't support FF 75.x :(

The add-on does its job. Mostly. Well, rarely. Try it at AMO. It does not work. No dynamic theme creation is evident, just a huge static style for numerous web pages. How to change the dark theme? I hate that dark cyan. The add-on is a great collection of dark styles, no more.

I've been using this for years, and suddenly today, 2/28/2020, its being disabled? Please fix this, I can't bear to look at white screens anymore

Though it changes the colors of the site, it's not really a reader; tiny text remains tiny. It's just a dark theme. Also, the dev tools button doesn't work.

Makes the new tab page white which is very annoying. Otherwise great extension with lots of customization.
