It was relatively good until recently, when it was automatically updated, and after that I could not see the bookmarks in the bookmarks sidebar, nor the menu bar. All was just black, except for the icons for the bookmarks in the sidebar. It became useless
Eventually I figured it out.
So here is how it should be explained:

Open the settings of the Dark Reader > Click the "More" tab > Click "All Settings" > Click/toggle "Change Browser Theme" so that it says "Default browser theme is active".

If you want some custom browser theme, install it or enable it AFTER all this procedure through Firefox Themes settings. You actually may need to uninstall and reinstall the Dark Reader extension and revert to the default Firefox browser theme in the Firefox settings before all this.

Excellente application, je l'utilise depuis plusieurs années. Petit souci avec la dernière version 4.9.97 qui va trés vite être réglé, j'en suis sur. Grand merci pour le tout le travail.

this app is excellent, it saved me a lot of fun and navigation on my nights out :D i highly recommend it!

Made an account just to leave this review, which is long overdue. This add-on enables me to use almost any website effortlessly while healing from debilitating photosensitivity. I simply could not have used most of my favorite websites for the last year without it. Any bugs that might arise from other sites updating are SWIFTLY addressed by the developer and with transparency for all users. The dev tools under the hood are robust, and so any site with niche use cases for my personal needs are also accessible. I wish I could throw money at the dev for providing an invaluable tool for so many people, working tirelessly to uphold its quality, and helping so many of us use the internet without pain. I hope this review, and the hundreds of people I have recommended this app to (many of which are abled but just enjoy reduced eyestrain now!!!), can be the next best thing!

The best browser add-on I've ever seen

La mejor extension para esta funcion.

Absolutely essential for me to use the web. Works out of the box on 97% of websites and is easily configured to work or temporarily disabled on the other 3%.

Dark Reader is a cool tool for those, who prefer to read the web in a dark environment. It offers to change websites to a dark version, that otherwise do not offer the option. But if a site does offer already a dark theme, Dark Reader offers users to opt out from altering an already dark site to it's dark version. It is also possible to disable darkening sites all together. The preview interface (which I can't wait to see fully implemented) also support dynamic switching to a dark theme.

The author faces many uphill battle to support this add-on, and the fact that they still provide support despite all the backlash is more astonishing then anything. May be biased myself, it definitely deserves a positive rating.

Dark reader works very well for almost all websites, and I don't like browsing the web without it for websites that don't have a built-in dark theme. I don't like burning my eyes.

Seems to be not making my firefox tabs go dark anymore.

Cheers to the developer team for keeping us updated with the issues the latest FF update caused. Been using this extension for years both at home and at work and it's saved my eyes and sanity. Cheers, guys!
