Live Theme - Ambient light by Rotary26B

Live Theme is a live ambient light for your Firefox theme. Your toolbar follows what you are watching.

• The tabs, address bar and toolbars take the main color of the page in the active tab.
• While a video is playing (YouTube, for example), the color follows the video in real time.
• When you click it, the address bar follows your system theme (light or dark).
• Click the Live Theme button to turn the effect on or off.

Privacy: Live Theme works entirely on your computer. To pick colors, it reads a tiny, temporary picture of the visible page and of the playing video, in memory only, and discards it immediately. Nothing is saved or sent anywhere.

Only the focused Firefox window is changed. Internal Firefox pages (such as about: pages) keep the last color.
