Recently slowing down all pages on mozilla firefox and several other pages. If developers can fix this, this is the best extension. Please fix this "slowing down firefox" problem.

dark reader recently started really slowing down web pages like reddit. a shame because the contrast toggle is really useful

Nifty extension that does what it says and used to be really useful, it helps reduce eyestrain by giving me a dark mode on websites that don't have it. I used to leave it on all the time. But lately (past 2 months or so) it's been slowing down firefox and I have to disable it for the page to load properly. Really hope the issue gets fixed soon - if yes, 5 stars!

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.

daha iyi bir alternatifi olmasını dilerdim

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.
