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.

It is difficult to create an algorythm that would give the optimum result to every page on the net I imagine. That is why respect for the undertaking, thanks for delivery. The addon would greatly benefit from an integrated user feedback feature that just reports which site is with which mode is not working to arrive at an overview.

The only thing that would make this extension perfect for me is if your site lists could be synced across browser installations. Is it possible for extensions to use firefox sync?

桌面版算很好用，Android 上也可以用，真的很不錯。只是 Android 上會造成網頁載入要花更多時間，也會造成崁入式瀏覽無法完成正常載入。

Really like it, but it slows down firefox way too much

This is an awesome addon, very useful. However, I would love to see its performance improved. It clearly slows done the loading of a page, even simple ones.

Is is really a very useful addon, the only problem with it is that it slows down page loading. It is painfully so sometimes. Works better under chrome, i hope the developer will cope with this problem under firefox, too.

It's not perfect, sometimes I have to disable it on a page to fix errors and sutch. But it works fine for most sites and I don't like browsing without it.

Perfect! Reduces eye strain and probably reduces electricity consumption.

there is an all white time when load the slow website body,after that this DR works,please fix the shining eye

Very good look and feel on almost every page. This is however very CPU intensive (for example on Twitter.com)

good first impression
