Usually good, but for some reason sometimes it becomes so heavy it crashes my whole laptop.

Plug-in crashes pretty frequently and breaks websites. Otherwise, when it works, it works great.

Slows performance signifikant and makes some content invisible

A good dark maker, unfortunately it is very slow. very very slow. Have to deinstall it.

Das Add-On sah erstmal super aus, hat aber nach ein paar Tagen den Browser stark ausgebremst und teilweise andere Funktionen blockiert, musste leider deinstallieren; schade.

It modifies structure of web pages rather than just making them dark. Sometimes the web pages aren't usable because of this add-on.

Was really enjoying this extension until recently when it kills itself a few times a day. I have had to "turn it back on" because all my websites are burning my eyes 3-4 times a day now. Never had this problem until last week.

使用中表示が非常に重くなるページが出てくる。（価格コム等。）DarkReaderをオフにした状態だと違和感なく開けるが、広告が多かったり複雑でごちゃごちゃした作りのサイトの表示は厳しいかもしれない。

works decently on some sites, but slows my browser down a lot and breaks sites i visit fairly often - on firefox android

Causes the browser to bog down and will cause it to stop working and shut down at times.

This addon used to be great. now its only 'this extention is slowing down this page' error. when i deleted the extension, sites opened within 1 second again. so by default this addon slows down loading.

Is good, but unfortunately is changing themes of Firefox.

This would be an awesome extension but after some weeks of usage the signifcant performance degradation in surfing sites is not bearable, anymore. As long as the performance is so bad I'm not able to use it unfortunately.

I loved this ad on but it made my browser beyond slow, would recommend otherwise, looking forward to updates.

many bugs with pictures and popup elements.
Картинки при просмотре выходят за размеры окна и показываются не полностью.
Плохо работает отображение popup элементов.
В общем радость была не долгой. Снес.

It looks great and works as advertised. However it bogs Firefox down *very* quickly. After install I found tabs taking forever to load, links would hang after clicking them, and some pages would completely freeze in transition for almost a full minute. Closing firefox, shutting any process left in the control panel down, and reopening it will resolve the issue for about 5 minutes, and then everything hangs again. I've found a lot of dark mode extensions do similar things, but this one was the worst, and fastest, to do it. Uninstalling the extension resolved every issue I had, and if you're having similar issues you can see it's firefox by opening the task manager, selecting more details, and viewing the memory usage of the app before and after removing or installing the extension.

It could be better but it distorts some pages and makes the opening of pages heavy. He needs adjustment, he's got good potential.

2 stars for effectively giving me the ability to put dark mode on any website.
-3 stars for
1) making all my tabs run slower...significantly slower
2) not honoring my preference of not running the addon on certain sites. After setting a site to not use the addon when I return to the page, the addon will still sometimes applying theming to the page...sometimes incompletely. This sometimes caused text to become unreadable.

A change could be made to the addon to correct this...default to off. Let me set a preference for if I want to apply dark mode or light mode, and then let me turn it on rather than force me to turn it off when it doesn't work for a site. This would default to the addon doing nothing on any sites until I explicitly say I want to use it there. You could even set it so I can choose whether the addon is used by default or not used by default. Options are always good.
I have uninstalled this addon because of these problems. If I hear these issues have been corrected, I'll try it again.

I really enjoyed this until I realized it saves the sites you toggle even while in a private browser. If I'm in a private browser, I don't want anything saved. I don't care if I have to manually toggle the modes every time I open Firefox, I do not want my history saved in any way and this unfortunately does that. I even removed it and reinstalled it and it saved the old sites I had visited. Manually removing them is a pain. If this hiccup can be fixed, it'd be an easy 5 stars but my privacy concerns majorly knocked it down.

Would be excellent, if the exceptions list actually worked, unless there's something I'm doing wrong, I'm just gonna not use this.
