Frequently Asked Questions

How to support Dark Reader

  1. Install our iOS/macOS app.
  2. Install our sponsors' apps and extensions.
  3. Donate.
  4. Suggest to friends and colleagues.

The extension asks for permissions to read website data

The extension needs these permissions to be able to analyze and modify website appearence, determine if a website is disabled by your settings or to use site-specific rules. We do not insert ads and do not collect any data or send it anywhere. The extension is fully open-source and has no obfuscated code. Our monetization is transparent and is based on users' donations.

The extensions store page and settings pages remain white

The extension has no access to these pages.

New tab page and browser theme remain white

The extension cannot change the appearence of a new tab or browser (though in Firefox it can since version 60). We recommend installing a dark theme or new tab extension from extensions store.

Screen flashes white when opening a new tab or navigating to a website

Before loading a website, Chrome shows the theme background color by default. We recommend installing a dark theme from the store.

The extension doesn't work at all

If you have similar dark mode extensions installed, disable them, then reload tabs. Click Dark Reader icon, check if top-right button is set to On and that Toggle site is not excluding the current site. Open Site list tab, check that Not invert listed is selected. If nothing helps, something terrible has happened, e-mail us.

The website is displayed incorrectly or works slowly

Please send the website address, a screenshot, your OS and browser versions to our e-mail. We will try to investigate the reason, at least for a popular website. Also try changing theme generation mode or try using Light mode. Check that the website is not listed under Site list tab.

The extension doesn't work in incognito mode

Open chrome://extensions page, find Dark Reader, click Allow in incognito.

The extension doesn't work for local files

Open chrome://extensions page, find Dark Reader, click Allow access to file URLs.

Entire website is not displayed in Filter mode

If you are using Chrome for Mac OS, update Mac OS up to 10.13, this should update your video drivers. If you are using Firefox, this is most likely a browser bug, use another mode for such websites.
