This addon saved my life.

It really slowed down my browsing experience. It was so slow I had to uninstall. Looks like it works really well and has a lot of options. But this doesn't matter if it's too slow to use

Wonderful app. Yes, it does slow loading, but It is great to use if you are using a few tabs. there is nothing else like it despite its necessity.

Eversince, I changed my Ubuntu Theme to Dark mode, I experienced problems with many websites in Firefox because everything I typed had a white font. So I decided to install this extension and fixed the problem. Not only that, everything just look better.

Great idea but it makes pages slow. Needs to be addressed.

I want to like this add-on. I really do. I love everything else about it except it causes excessive loading times.

Let me get this out of the way: It's very well-designed. It does exactly what it says, and it does it in an intelligent way. It actually looks like an official dark mode on every site. The only problem is I can't use it effectively because it murders your CPU and nothing will load. And it's not like I'm on a Pentium 4 that can barely handle Firefox itself, I'm on a $200 hexa-core from 2 years ago running at 3.9 Ghz.

In short, it's well-done, but it's so poorly optimized it's virtually unusable. I would gladly go back to it if I could actually use it.

Absolutely life changing. Programming at night is much easier on my eyes now and I no longer need to get my sunglasses out when I open a new tab. I am genuinely impressed with how well this add on works.

nice mode but sometime memory leak over 6gb of ram especially when u go to EA website

works on some sites, but made gmail unusable and some sites stopped loading.

I love this extension!!!!
