It works very well on Windows. But the page doesn't turn dark on android.

it makes Firefox hang and so slow

Best "automatic dark mode" addon available. Does an exceptional job of dynamically making things dark with minimal errors. I can't browse the web without this now.

This is an essential plug-in for lovers of Dark screens. Also supports themes from Userstyles.org so you can get your customisation fixes without using Stylish and having your browsing history tracked.

DR is so much better than using dark styles from userstyles.org, because of it's dynamic analysis. It is rare to see images made negative, the per-site toggle is an amazing feature too when DR gets it wrong, which is also rare.

Thank you! I've been manually porting/compiling the Chrome extension ever since FF Quantum, but this direct support is really huge! DR was my Killer Chrome extension and now I'm finally free to use my fave browser Firefox exclusively.

Together with FF61's native Dark theme, and UI tweaks, Firefox is the perfect late-night hacking browser for web developers and webadmins.

Slows down Firefox so badly. Even slows down my TST set up, which is fine with other darkify extensions. The features and capabilities are amazing, but this resource hog made using firefox unbearable in some situations, so I have had to remove it in favor of a more simple extension that still gets the main job done without slowing down my browser.

Looks nice and has some customization options. A previous dark mode extension I used tended to break some website elements, but I haven't yet noticed any issues with this one. This also excludes images, which is nice.

you tub seed it was cool

Best night mode out of all . Works with Firefox Nightly .Other dark modes tends to break with nightly version but this doesn't .Love it .

this is so close to being perfect.

websites look great but some are running slower and giving errors. i'll check back in a month or two to see if it has been updated!

Pages load extremely slow after installing this extension. Besides an ad blocker, I have no other extensions installed and I found that some pages wouldn't even load without a "stop script" pop-up.

Приятно для глаз, благодарю.

После установки расширения, ни сайты почти не грузятся, ни сам браузер. Даже в настройки с трудом входит, чтобы удалить расширение.
Firefox Quantum 60.0.2 (64-бит)

Beautiful dark theme. Save my eyes. Must have this add-on.

Just about perfect!!!! THANK YOU!

Simple to use, working and open source ! Just Perfect.

Where have you been all these years. Must have for every Firefox and Chrome user!
