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.

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.

One of the OG addons have to be removed finally. Loved this addon for years but its at the point now it is very noticeably slowing down my pages. Sometimes to the point of freezing the entire browser.

IMO the addon needs to be rebuilt from the ground up.

Great full featured Dark Mode add-on that has been steadily improving over the years. It's not perfect, but it's very close and much better than other add-ons. The only thing better than this add-on is for the webpage itself to have a dedicated dark mode. But for the rest of the internet, this add-on is pretty solid.

Was working great for a number of years, but recently grounded my web pages to a halt. Had to remove it.

Well, I would give 5 stars, but it seems to have not been updated recently and is now tanking performance. I had to uninstall sadly.
