Just installed the latest version of jessie on my pi 3 and installed chromium 50. Works great as it always did.
i tried the chrome://flags trick and disabled the media source api,
and at last youtube browsing works at 360p inside the browser with no pauses or excessive dropped frames.
Plus i tried the online theramin page, not expecting it to work, but it works ok as well
Will chromium browser, ever be installed by default into the rasbian images,
i know this is a touchy subject, but they shoukd think about it.
i mean the default browser they give, uses ' duck duck go' by default
