808041 - Youtube video links on web pages create moments of unresponsiveness

Status: RESOLVED WORKSFORME

(Firefox :: Untriaged, defect)

Description

[J]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko/20100101 Firefox/16.0
Build ID: 20121010144125

Steps to reproduce:

Browse forums with embedded Youtube links. 


Actual results:

It makes Firefox unresponsive for several moments only when you mouse over the embedded video graphic (but not clicking). It's obvious because the mouse cursor turns into a hand, then you can move away from the graphic and it stays a hand for several moments. But the longer you leave the page up, the quicker it responds. Eventually going down to about 1-2 second response. I have the latest Firefox and Flash afaik (just updated them). Flash 11.4.402.287. Firefox 16.0.1 (ok, i see there is yet another update, I'm about to apply it and see if that helps).

It is on this site: http://www.teamliquid.net/forum/viewmessage.php?topic_id=379599

And it has been happening ever since I updated Firefox and flash about a week ago, and still after another flash update this morning. About to update Firefox again. 


Expected results:

Cursor should have been nearly instant response when I simply mouse over the graphic and continue past the graphic.

This is a deal killer for normal browsing. So many youtube links all over, sometimes I have to manually kill Firefox and use something else because the slowdown becomes too much.

Updating firefox to 16.0.2 has not helped. 

Note that if I go to youtube.com and browse around the front page, I have no noticeable issues.

Buuuut, if I go to that specific embedded link there is a problem. And playing youtube videos in general seems to be a problem now. I can play them in IE and Chrome no problem though. What is going on.

I've tried disabling all extensions as well. No luck.

Reporter, could you try:

1) With a new profile: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles (don't import anything)

2) With protected mode disabled in Flash 11.4:

Does it improve something?

Hi Reporter, 

Loic's suggestions have helped you to solve the issue? 
If not can you please test this on the latest Firefox release (43.0.4) or latest Nightly (46.0a1, https://nightly.mozilla.org/) and tell me if this still reproduces for you ? When doing this please use a new fresh Firefox profile, maybe also in safe mode (https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems). 

A lot of things changed from Firefox 16.0 and also the flash plugin received several updates. Your issue could have been fixed along the way.

Thanks,
Cosmin.

Maybe that would have fixed it. Eventually I got a new PC and never had the problems after that and cannot reproduce at this time.

Based on comment #8 I will mark this issue as Resolved - Worksforme.

Thanks,
