All video players on Firefox lose sound and stop playing

Any video player I play will randomly lose sound and a few seconds later stop playing. I've noticed that this happens when I have two or more tabs with video players on them. Having only one tab with a player, be it youtube, jw player, or veever, does not cause any problems. Having two of them out at the same time causes the problem to occur.

I believe this happened around the time I installed winzip and Windows XP Mode onto my computer, but I have since uninstalled XP Mode.

I use an Acer computer, Aspier 4830T-6841, windows 7.

Please check if all your plugins are up-to-date. To do this, go to the Mozilla Plugin Check site.

Once you're there, the site will check if all your plugins have the latest versions. If you see plugins in the list that have a yellow Update button or a red Update now button, please update these immediately.

To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

This didn't solve the problem.

Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox are most probably caused by a recent Flash 11.3 update and/or a malfunctioning Real Player browser plugin.

In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

The problem here is that Flash isn't crashing, it's the video just stops dead in its tracks after losing sound. I can set the cursor to the start of the video or other points and the video will work perfectly well for a while before the event happens again.


I can try out downgrading to flash 10, but I don't think it'll help.

I am having the same problem. Any time I am watching a video, I lose sound first, video plays for a few seconds, then freezes.

I don't have problem with this on Chrome or IE.

The problem occurred when i updated to the latest flash.

You can check for problems with current Flash plugin versions and try these:

  • disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
  • disable protected mode in Flash 11.3 and later
  • disable hardware acceleration in the Flash plugin

Try to disable hardware acceleration in Firefox.
