Build ID: 20121024073032

Steps to reproduce:

Tried to view videos in the URL: 

Actual results:

The video is stuck with the message "Optimizing Video Quality" 

Expected results:

The video should have played normally. this is not limited to only this Ted video. This seems to happen for all videos. I even restarted the firefox with add-ons disabled, but the issue still exists.
wfm with Firefox 16.0.2 and flash Version: 11.4.402.287
I see the message during a fraction of seconds, but then the video plays normally.

Could you try wit a new profile, please:

I tried with a different profile option too. but, the issue exists.
My machine runs on Windows 7 32 bit and version of firefox is 16.0.2
anilkumar, what's the Flash version on your machine?
Flash version is 11.4.402.287 ,OS is Windows7 (64-bit) and browser is 16.0.2 Firefox.
I just now upgraded to the latest version of flash, that is, 11.5.502.110 .
Even then the issue exists. I found out the version of flash from this URL -
I still see the same issue when I launched the Firefox in safe mode.
thanks for responding so quickly..
Is it the same issue with another browser, like IE or Chrome?
I have checked in IE browser and it works fine. I have also tried in Mac Firefox where it works fine.

The problem seems to happen only on windows7 Firefox.
IE is using a complete different plugin (activex).
You might want to ask at the support under We can not reproduce the issue on our systems.
I´ve experienced this problem and I´ve found out HTTPS Everywhere (at the least version 3.0.4) causes it. To work around this problem you could disable the 'TED (partial)' rule or HTTPS Everywhere completely.

Bug filed:
I asked to the reporter to test with a new profile (without re-adding any extensions), so HTTPS Everywhere should be missing from this test profile and not interfer with the website.

anilkumar, do you have this extension?

If yes, try in safe mode and confirm it works as expected:
Flags: needinfo?(anil.kuppa)
I don't have this extension. But, I tried in safe mode and it doesn't work.
I also tried in Chrome and it doesn't work. I'm able to play Ted videos only in IE. Could this issue be because I'm at office? Maybe, it's because of proxy.

>Maybe, it's because of proxy.

Yes, likely. Proxies do often nasty stuff. Could you try at home, please?

Resolution: --- → DUPLICATE
Aside from HTTPS Everywhere versions prior to 3.1.1 (which I'm about to release), another thing that seems to break this video is blocking Flash cookies.
