Крайне приятное дополнение, однако при использовании его в вк есть один неприятный момент: в диалогах значок онлайна с пк отображается не привычным зелёным, а болотным цветом. Отображение онлайна телефонов - отлично.

Worked just fine for a couple months, then Firefox quarantined it (when it was still named Dark Mode and wasn't recommended yet), this message appears below the disabled and locked out "Dark Mode" :
Dark Theme (Malware) has been blocked for your protection.

Why was it blocked?
This add-on violates Mozilla's ad-don policies by using obfuscated code.
What does this mean?

The problematic add-on or plugin will be automatically disabled and no longer usable.
When Mozilla becomes aware of add-ons, plugins, or other third-party software that seriously compromises Firefox security, stability, or performance and meets certain criteria, the software may be blocked from general use. For more information, please read this support article.

Blocked on Feb 28, 2020. View block request.

Now I'm using the slightly inferior Dark Night Mode add-on, because I can't stand all that LED light at night, especially that harmful blue wave we experience that seriously messes with the circadian rhythm/sleep cycle (like those new LED streetlights, im glad my city still mostly just has the orange sodium lights and hope the newfound harmful health effects slow down the deployment of that even worse light pollution).

Mr. Shutau, can I trust your new "Dark Reader" or will it attempt to inject malicious code sometime in the future? I really liked your "Dark Mode", but using Debian Linux, I was surprised to see the word Malware in my add-ons when I went to the Add-Ons menu when I noticed the extension stopped working and the icon disappeared from my toolbar.

If an explanation of what happened here can be obtained, I'd love to see it...

It's great idea, I probe it and I like it, but it doesn't works properly in my firefox, it makes it works slow, and I can't be waiting for a web because Dark Reader is working. ¡¡ What a petty !!
Es una gran idea, la he probado y me gusta, pero no funciona en mi firefox, lo hace trabajar lento y no puedo estar esperando a una web por que esté trabajando Dark Reader. ¡¡ Es una pena !!

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

Looks good but a tad heavy and contrast is too low. Would be nice to be able to have sepia / grayscale while still being able to distinguish links.

So much lags, lags in many sites, also no updates....

hate that white flash it makes on Google.com
it makes my eyes hurt everytime

目の負担がとても減った。これ無しではブラウザは使えない。
最近のダイナミックレンジが広いモニタでは、白色が明るすぎて目に刺さる事が多い。

サイトによって表示が崩れる場合があるが、ページ毎に無効にしたり、モードを切り替えたりを記憶させる事ができる。

【欠点】
表示モードにもよるが、負荷が高め。ラップトップでは使いにくいかも。

【改善要望】
・ページの背景色によってON/OFFする機能が欲しい。黒系のページであっても反転させてしまい、白系の見ずらいサイトになってしまう事がある。
・ページ毎の設定をブラウザ間で共有したい。クラウドストレージ等にconfigを保存できると良いかも。

СУПЕР спасибо за правду!

It's very easy.

very easy to use

Today, my firefox refused to start tabs, they were crashing (facebook twitter etc.).

After investigating, Dark Reader was the cause, once disabled, my firefox is working again and much faster.

Must be something wrong with this extension.

Salvage for eyes!
