Yesterday I could watch videos at the Khan Academy site, today they don't work. Instead of the video I get a black screen with a link to "Get Adobe Flash player". Clicking the link takes me to a page telling me "Your Google Chrome browser already includes Adobe Flash Player built-in. Google Chrome will automatically update when new versions of Flash Player are available." All sites with embedded YouTube videos have this problem.

Here's an example of a video that doesn't work: https://www.khanacademy.org/video/unit-circle-definition-of-trig-functions-1

Here's what I see instead: enter image description here

And the Adobe Flash page: enter image description here

The above video plays fine in Firefox, as do all other embedded YouTube videos.

Watching videos at youtube.com still works.

I have cleared everything since the beginning of time with Tools->Clear browsing data.

  • I see you are using an adblocker. Try disabling it and refresh the page.

  • update chrome, if that didn't work, reinstall it, some extension break chrome, my chrome stopped working completely because of a speed dial extension - disabling extensions won't fix it, a bad extension will break chrome and reinstalling is the only option, trust me, i know, happened to me, not with youtube though

  • @PeterMaxwell: I disabled Adblock Plus and reloaded the page but the problem persists.

    I would try what @Fischer said, but just disable all of your extensions instead of re-installing. That should give you the same affect. If it still doesn't work, try disabling flash in chrome://plugins/ restart chrome then re-enabling it.

The FVD Video Downloader extension was the cause of the problem. Disabling it fixed the problem.

Thank you to the commenters for steering me in the right direction.
