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!

The best dark reader extension available - outstanding work! Ignore the recent 1-star reviews about Reddit's website - the bug was introduced by a recent update by Reddit itself, and the Dark Reader developers quickly worked to address the issue.
If you're a (long-time) user of this incredible tool, please consider supporting the developers through a donation to help them continue their fantastic work. It's discouraging (and counterproductive) to see users who have benefited from Dark Reader for years suddenly leaving negative reviews at the first sign of a problem, instead of reaching out to the developers or checking for updates first.

This is one of the most vital and effective add-ons I've ever installed. Not every website/browser/etc has a consistent dark mode, and none handle it as well as Dark Reader. Needing to constantly research, this add-on saves my eyes at night. Even with recent changes to FireFox which temporarily hampered performance, Dark Reader quickly pushed an update and is straightforward about addressing issues. Honestly, this is probably one of the best add-ons next to an ad-blocker out there.

This extension is a huge difference maker for me, and for so many people, reducing eyestrain and promoting eye health. The internet is always changing and squashing bugs is a constant battle. So thank you Dark Reader for your hard work!!!
I want to contribute some encouragement and I will contribute cash as soon as I'm able.
Edit: For users who may need to disable this on a specific website: First, go to the website where you're having issues, then open the extension menu (you should see only your active extensions). Select Dark Reader, then uncheck "Enabled for current website". The menus are different between desktop & mobile, but it's fairly easy to figure out.

Not works on Mozilla.org page. All other perfect

Thanks Dark Reader team for taking care of our eyes.

To those with v4.9.97 breaking Firefox: Just realized that the Developer's note applies to Settings on DarkReader, not Firefox. Go to the DR icon on the top of your window and choose "MORE". It is to the right of "Filter". Then choose "Default" below.

With last update I got blank black window and menus in firefox
Update: disabling custom theme solved my problem, thx!
