Used this extension for many years and loved it. I had to remove it recently as it was severely slowing down my web pages. sad

by far the most polished dark mode addon, for most people this is the one you want to use. unfortunately for mobile users who prefer to browse x.com (formerly twitter) with adblock instead of through the android x app, this extension will slow your phone to a crawl after a few hours of browsing, forcing you to clear data and quit firefox. long story short: this is a great extension, but it's not updated regularly enough for anyone to consider donating, it's clearly abandonded. check out "Dark Background and Light Text" by Mikhail Khvoinitsky for an alternative darkmode extension on Firefox

It breaks too often and when it does it locks up your browser for an extended period of time.

It struggles on far too many websites and ultimately slows down the majority of website load times. Things once blinked to load and this extension makes them hang.

Sad because it use to work a whole lot better, but I find myself disabling it more and more to the point Im wondering why I even keep it. I also think this is the cause for locking up the entire browser every once in a great while.

If this isnt updated to run with reddit I'm going somewhere else. This month this addon has been crashing my browser.

Works on most sites, though there's currently a memory leak issue when using it on Reddit. Memory usage climbs to 6GB+ for a single tab. I'll update my rating if it's ever fixed.

Slows down reddit to the point that it becomes completely unstable and cant load new content

Really solid extension. Clean and lightweight, fits perfectly into my workflow. Does exactly what it promises.

Everything's fine, but the constant flickering on some grey-scale gradients is just incredibly annoying

latest May 7 version makes reddit totally unusable, crashing the site

With the latest Firefox update (version 150.0.2, May 7, 2026), this extension causes slow-down in the Reddit website, and only there. Screen updates lag or become unresponsive for long durations on the Reddit site. Firefox then shows a notification bar right below the address bar saying Dark Reader is causing the slowdown. Please fix if you can.

Esta extensão salvou meu dia! (E meus olhos!)

Works pretty well, but they broke something with the most recent update, and it's causing a huge memory leak. I had to go back to 4.9.124

Used to be great, but more and more it'll make some sites like run 10-30x slower until they crash your browser tab. (Tested and confirmed it was this extension)
