The extension is great and all but the problem is it really slows down page load.

1st, I really love this add-on and it is so much better on my eyes being dark, thank you! I has been running great since I installed it 2 months ago. However, I now am having issues with the script, where a popup will ask me to temporarily stop Dark Reader, wait or stop. I am using a good laptop, running Windows 7. I really hope there is a fix for this or you can help me fix it. There may be something on my side I need to adjust. There is nothing I did to have this happen with the add-on.

Amazing extension. Could be more light weight tho.

Best on desktop, good on mobile.
Maybe this wasn't developed with the android version in mind, but it does work on it and I have two minor issues: it flashes a white page on some page loads and it seems to be quite heavy for my Nokia 6.1., which leads it to crash every so often.
Other than that, great! Why does the internet still stick with blinding white pages with black text..

見やすくていいんだけど、webの読み込みが重くなる。残念だけどこれからの開発に期待してます。

The extension is fantastic, far better than any alternative I know of.

BUT: it seems to run significantly less smoothly than on Chrome, specifically running horribly on Google sites (Gmail, Calendar), Facebook and others. If you could some how address this issue it'll be great.

good!

Really good but perfection-able: a function to change the font's size would be useful.
Sometime slow with some sites.

Works really good.
It's only one star away from being top rated for me because I think the options menu could use a clean up its really messy.

AND its missing a feature.... i want Dark Reader to be by defaule OFF on all websites so that i can enable the ones I want to be dark individually myself, right now the reverse is true but i want to be able to pick what my own default is

Sometimes tends to block browser for a few seconds (when switching pages or toying with add-on settings), as if the add-on was doing too much computation. Could use some optimization I guess.

ALMOST.... Perfect. Everything my eyes needed since then. Although, I wish there's an automation button that automatically darkens the website since I don't want to toggle every time I visit a new site. However, it's still an helpful app tho!

This Extension provides excellent dark themes on almost all websites. But when I visited sites such as redhat.com/en/blog/..., my CPU usage went all the way to ~90% (a fairly new Intel i5) and RAM (4GB) continued being filled up until the whole system crashed.
