Solution: This issue has been fixed in Firefox 13.0 release. If you are running an older beta of Firefox 13, please update to the release channel.

If anyone still experiences this issue, please respond to this thread with details.

I was directed here from my question: "Flash video stops and starts but audio continues"

Flash videos freeze momentarily then fast forward/catch up while the audio continues to play without a problem. Interestingly, I noticed on one video it freezes at the same spot (about 27-28 seconds in) each time I try it. Audio does continue for a split second after I close a tab (that's normal) but it does not keep going and I don't have to restart FF to stop the audio. Also, I am already using FF13 and it didn't resolved my issue.

I'm using Win XP with FF 13 but the problem has been going on for about a month (ie under FF12 as well). The problem also occurs under IE which makes me believe that Adobe Flash is the culprit (I also tested Quicktime videos and they worked fine). Flash video seems to work fine under Win7 (rarely freezes) and Ubuntu.

I looked through similar questions (see above link) and did find one thing that works but it is only a temporary fix for me. One person had HTML5 problems and had to opt out on Youtube. I did the opposite - I opted in and the videos worked fine. However, I like to stick on private browsing which would require me to 'opt in' each time I go to Youtube. Additionally, I encounter the same problem on other sites with flash video and they don't have an HTML5 option.

I also noticed that I do not have the problem at work on an XP machine with same addons in FF. Flash is v11,1,102,62 (at home I think I have the most updated: 11.2.202.235). I updated the XP machine at work to the latest flash and it still seems to work fine.

I have tried uninstalling/reinstalling flash, starting FF in safe mode, turning off my firewall and I my internet speed is fine (15Mbps down). I thought it could be my video card but videos on my computer play fine as did the quicktime video. I'm at a loss.

Have been having the same problem since FF 12, am on 14 now and it still happens. Only stops playing audio when I restart FF. I am using XP4. Have latest plugins.

I Could Not Terminate BBC World Service Audio Until Adobe Flash Player Reinstalled

This is NOT fixed. I have the latest Ubuntu and Firefox 15.0.1, and the issue is very much present. I'll have to use Chrome until you brainiacs manage to fix this pathetic bug. Maybe I won't come back.

When my audio won't quit - which only occurs occasionally when streaming BBC Worldwide Service - I go through my History to find I have two (2) BBC links open. I've successfully terminated the un-wanted audio by removing BBC from my history. As I rarely stream, audio persistence does not especially bother me, though in his particular matter, FF is not yet ready for prime-time. Otherwise I'm very pleased w/FF 15.0.1.
