YouTube HTML5 Unresponsive Script Error

With YouTube HTML5 mode (http://www.youtube.com/html5 ) enabled, any video played with the HTML5 player will give me a unresponsive script error on "Script: http://s.ytimg.com/yt/jsbin/html5player-vflGWJljH.js:58"

Note that not all videos play on the HTML5 player. Try this video: http://www.youtube.com/watch?v=cdgQpa1pUUE

Howard Forum Wiki gives me unresponsive script error as well. Go to http://www.howardforums.com/showwiki.php?title=Android+Wiki:About and click on the Discussion tab and I get an error from "Script: http://www.howardforums.com/clientscript/vault/reset.js?v=3014:285" script.

Google know about the issue, and they should be updating the website later today.

Re: YouTube HTML5 Unresponsive Script Error

Re: YouTube HTML5 Unresponsive Script Error

had the same problem since upgrading to 14.

tried downgrading to 13 but for some reason the problem came with, probably because i didnt do a full uninstall and erase of settings.

anyway, go here http://www.youtube.com/html5/ and opt out of the trial.

if you read the script error it always has to do with html5 so i figured that was the issue.

Re: YouTube HTML5 Unresponsive Script Error

I see the same happening with that video, so it looks that the script isn't fully compatible with Firefox.

Same problem and has caused BSOD when trying to load.

Tried extending the time FF will wait for script to load as well and just causes browser to freeze.

Re: YouTube HTML5 Unresponsive Script Error

This is definitely not a Firefox 14+ problem! I had the same "Unresponsive script" popup with the YT HTML5 player using Firefox 11.0 on Ubuntu (10.10). I guess YouTube did some "upgrade" that didn't go quite well. Probably somebody missed to run a few unit tests or failed to submit the new code to QA for an UAT before deploying it to production ... :-(

So far the only workaround I've found is to leave the HTML5 trial on the YT page (http://www.youtube.com/html5/) and use the flash video player. :-(

The HTML5 player works with Chrome v20.0.1132.43 though ... I guess they did test only on Chrome. :-(

P.S.: I did test this with a completely new+clean Firefox profile (created a new profile, visited the YT HTML5 trial opt-in page and enabled the HTML5 player, then visited a YouTube video with the HTML5 player and got the "Unresponsive script" error/popup). And on the same computer with the same installed plugins (+versions) this worked without a problem just a few days ago (I guess the problem started occuring sometime yesterday or maybe the day before that ... I'm not quite sure).

Re: YouTube HTML5 Unresponsive Script Error

mazurkfsflip is correct. Its an HTML5 youtube - firefox incompatibility. Go to the link in his post to opt out of the HTML5 trial and problem solved (for now).

In order to fix this problem go on the HTML5 page ( http://www.youtube.com/html5 ) at the bottom of the page, you will see "You are currently in the HTML5 trial." and "Leave the HTML5 Trial". Click on the second option and you will get rid of this error.

Re: YouTube HTML5 Unresponsive Script Error

Thanks for the tip, it worked. However, clicking on the link you left gave a 404 error, but going to youtube and typing the html5 part worked. Smiley Happy
