About this extension

What Does The Add-on Do
Every time you open, close, or switch tabs, this add-on changes the theme of your Firefox browser to match the theme color of the website you are viewing – just like how macOS Safari tints its tab bar.

Works Well With
This add-on is programmed particularly to be responsive to some prominent web page styling add-ons.

Incompatible With
This add-on takes control of browser’s UI color and color scheme settings. Any add-on that makes changes to them is incompatible.

Firefox under Version 58.0 (released on Jan, 2018)
Chameleon Dynamic Theme
VivaldiFox
Dark Mode Website Switcher
automaticDark
Envify
Midnight Lizard

Safety Warning
Beware of malicious web UI: Please distinguish between the browser’s UI and the web UI, see The Line of Death. (Credit to u/KazaHesto)

For CSS Theme Enjoyers
A CSS theme can work with ATBC, when system color variables are being used. This is an example of an ATBC-compatible CSS theme.

Known Issues

“about:devtools-toolbox” might not have the correct color scheme
