Extension summary

Analyze keywords

Obscura reduces blue light from web pages, making it easier to fall asleep.

Simple controls: on/off button, and a color picker.

Respects your privacy: no trackers, no ads.

Permissions: this type of extension requires the "can read and change your data" permission, even though it does not actually read any of your data. That's why I wrote this extension, and it's why I try to keep the code short - so anyone can look at the code and be sure it is not doing anything nefarious.

Note: that this type of extension does not work on the Chrome Web Store pages, you'll have to visit a normal page to see the effect.

You're encouraged to examine and audit the code yourself, it's relatively short at 58 total lines of JavaScript.

User reviews

Great stuff. Thanks for making this, it's really refreshing after wandering through an endless sea of paid promotions, spyware, and non-functional extensions to find something which immediately upon using I see a noticeable and positive difference. The UI frankly isn't pretty but it's intuitive and works well. Only change I'd recommend is a note when on the extension store that extensions don't work~ I always forget that and spend a minute wondering why nothing is happening before realizing that I need to change to a different page to see a change.
