Leider funktioniert der dark reader nicht richtig, in fennec , Android Pie. Einmal kann ich das Farbschema / Theme umschalten, aber wenn ich browsertab umschalte, oder eine Seite neu lade, ist die Seite nicht mehr im dark oder welch auch anderem Theme.
Wenn ich dann die dark reader-Einstellungen laden will, gibt es sinngemäß "Einstellungen werden geladen, bitte warten, aber passiert nichts.
Einzig in den AddOn Einstellungen von fennec kann ich den dark reader deaktivieren.

Just too slow, too much delay. Not worth it overall.

Change colors pretty well, but it causes a lot of pages to load very slowly, in stages, and in the meantime sometimes it'll be half dark, half white, stark eye-straining contrast.

well it works, but does not work as i need it to. i want it to be off and only toggle on for specific pages, not HAVE to be on all time for all pages just to toggle it off again for all the pages... just for the sake of having a few pages in dark mode. and it slows down the browser a lot on my low-end notebook. the devs should should check out how this extension is really annoying on different artists bandcamp pages. i listen to a lot of music from there and have to toggle off for pretty much every single page. i also have to say that i tried out about 2 years ago and still the same issue. just not for me...

these two days are not working

Love the idea but it's janky. Some sites look odd, which is fine as you can disable per site, but i currently can't as the shortcut isn't working and the menu has stopped working properly. Also causes a slight delay in loading sites that it's turned on for.

I have two problems with Dark Reader. (1) When I change to a new tab or new content for a tab I typically get a bright white initial display before Dark Reader kicks in to style the new content, completely dazzling my dark-adapted eyes and obviating the point of the extension and (2) Critical content is often unreadable using Dark Reader. I'm guessing that the first problem is not easy to address given the self-imposed limitations of FF's new extension mechanism!

This add-on sometimes works like a charm, but often breaks webpages, making them unusable whether or not I toggle the add-on on or off entirely or for single websites. The add-on often makes necessary navigation text and links unreadable/invisible. Also, removing the add-on does not remove the CSS from these pages, I probably need to empty my caches.

I usually like to use this extension on Edge browser. However, it slows down Firefox, significantly. So, I disabled and stopped using it until developers fix it.

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.
