YouTube watched videos are remember being watched after closing private session. Steps to reproduce: 1. Close ALL Mozilla Firefox windows. 2. Open new private window. 3. Watch an YouTube video you haven't ever watched before. 4. Close private window. 5. Open new private window. 6. See that the previously watched video is now labeled "WATCHED".

This is so serious that is could lead to a law case.

hello, when i try this i don't see any youtube videos being labelled as watched (also in the same session) - is this a feature once you're logged in to youtube or that is provided by the "YouTube Center" addon that you have installed?

There are other things that need attention.

Please update the Shockwave Flash 16.0 r0 plugin. The currently installed version is outdated and has known security vulnerabilities.
