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

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.

From my experience of using the extension, the add-on seems to be unsatisfactory at best, and unusable at worst. For instance, basically every site that I visited had the logo at the lop-left corner of the screen blend in with the background in terms of color. It will also sometimes just not work as expected, and by sometimes I mean almost all of the sites that I visit. Even the site on which I'm writing this review (addons(dot)mozilla(dot)org/) is in white mode while running the extension. You should really fix your utility before asking users to donate $10 (which happens immediately, mind you).

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.

Vamos dizer que...essa extensão salvou meus dias! (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)

Works most of the time but makes many pages unbearable slow.
