Is YouTube High Definition safe?
YouTube High Definition sets video quality on YouTube pages and broadcasts the extension's runtime ID via window.postMessage on each load.
The extension injects a content script into YouTube pages that applies user-configured quality and resolution settings by posting messages to the page context. On install, the background opens a page on barisderin.com. The content script broadcasts the extension's internal URL (containing its runtime ID) via window.postMessage with a wildcard target, which any JavaScript running in the YouTube page context can read.

Where it sends data
Destinations our analysis observed YouTube High Definition contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
