789611 - YouTube videos won't play with latest stable release (15.0.1)

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

[kaizander]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0.1
Build ID: 20120905151427

Steps to reproduce:

I tried to play YouTube videos just after the recent update to 15.0.1.

Note: The HTML5 YouTube player still works fine.

FF 15, Chrome and IE9 play those videos, FF15.0.1 won't.


Actual results:

The YouTube player said "An error occured, please try again later.".
I tried this on multiple (about 20) videos, most of which I remember watching with FF 15.

I'm in the HTML5 trial for YouTube, which plays videos without ads in the HTML5 player. Those videos play just fine, but if I leave the trial or try to play videos with ads, they won't play.


Expected results:

Well, it should play normally, as the previous version did (15).

The issue is a bad interaction between Flash player and Realplayer, see

I could resolve this problem by creating a new profile. It seems like the update corrupted it.

I tried FF 15.0.1 on two more machines where it ran fine. So it was a problem with my profile.
