This is the addon you really want when it comes to dark mode. It is brilliantly simple and thus very fast. The default "Stylesheet processor" works rather well with most web pages and when it doesn't "Simple CSS" is the next best thing.

This is my default for a global and consistent "Dark Mode". I've even tweaked it to make it "Solarized Dark", essentially; paired with the "ZenFox" addon for the Firefox UI part. And only when all options, including "Invert", fail, do I manually enable "Dark Reader" for the site in question, and I almost immediately regret it, because it feels like molasses compared to this fine gem of engineering excellence; thankfully, those occasions are very rare.

Great extention

pretty customisable! I like the options for different methods of making a site dark mode. "Just works".

WOW! Vor 5 Jahren zuletzt aktualisiert, trotzdem 1A in Funktion und sehr Ressourcensparend! Okay, nicht so viele Einstellmöglichkeiten wie bei der anderen bekannten Dark Erweiterung, aber das brauche ich niemals. Alle Webseiten super im Darkmodus und sehr wenig Verbrauch an Ressourcen = sehr gut!!!

WOW! Last updated 5 years ago, but still works perfectly and is very resource-efficient! Okay, it doesn't have as many settings options as the other well-known dark mode extension, but I never need those. All websites look great in dark mode and it uses very few resources = very good!!!

Absolute garbage. I finally figured out this extension was slowing down firefox massively and holding up pages from loading after loading firefox.

I never write reviews for extensions but, for those suffering and or struggling with vision issues this extension is going to help you. I was running DarkReader and thought it was good - little buggy / wonky and broke a lot of things and caused frustration regarding always messing with parameters that never helped my vision. Sepia changes always riding the faders so-to-speak and then setting websites in memory "only for site x". Forget that.

Firefox background tweaks mess up the entire browser and skin the entire side panel (Sideberry) and blankets themes and mucks up the vision. Ditch that. That's never going to help those suffering with vision issues.

I stumbled upon Dark_Backround_Light_Text and in a matter of a seconds I discovered this is the tool I needed all along. I finally found an extension that's simple to use that doesn't muck up the browser skin, doesn't mess up the side-panel (Sideberry / Tree-Style-Tabs) theme that goes with the browser skin / theme and allows the background and font colour to be changed.

Example: Gmail online theme is no longer impacted. Just the text and background colour. There are some buttons that don't get outlined and/or are blank thus, it's not 100% bang on but, for me, just changing font and background colour for night mode is heavenly.

I had issues with white glare out / white-smokey haze and do not run day mode at all. Night mode is bad as well for, white font colour makes it glarey on a jet black background.

I don't like white font colour but terminal font colour on a greenish blue RGB background like I've setup in all my software programs.

There are other advanced tools such as Stylus and or Tranquility Reader - they do work however, when you need to get things done (GTD), this tool is a global parameter thus, you don't need to learn how to code in HTML and CSS mode just to fix a site's font issue due to poorly chosen colour schemes.

Greatest Extension I've found so far for me eyes. Excellent work mate.

Breaks twitter and some other sites, otherwise, it is a simple and lightweight darken option

AWESOME... Works every time. Simple and does as it says without a bunch of settings. Don't have to reset it every few times of use unlike another extension I tried.
THANK YOU!

Thank you for addon works fine...

I appreciate that DBALT is simple to use and easy to understand at a glance. No special rules or set up needed. I've been using it for years and recommend it to anyone who wants their internet easy to read.
