A browser extension that automatically switches Google accounts when visiting www.youtube.com and music.youtube.com.
On installation, you get to choose which account should be used on each site. You may also change this at any time by clicking the extension icon.
YTMAS fully relies on how YouTube structures their websites. I didn't find any API and therefore decided to simply simulate mouse clicks on certain elements. This also means that the extension will probably stop working (until adaption) whenever there's a new design update from YouTube.
The icon includes Font Awesome's user-circle and is used under this license.
