Flash Player Choppy And Stuttering In Firefox 13

Specifically, the problem is this. When using a Flash player (audio or video) on any web page, while doing activity in another tab or window on the same browser, the sound or video stutters and chops up. Like, just mousing over links in a webpage will cause the sound to jump and stutter in time with the mouse actions. Happens with embedded audio players and video players alike. Really annoying. I reverted to an older Flash version a couple weeks ago and that fixed the issue.

I also posted about this in the Adobe Flash forum, since the problem arose when updating to the latest Flash Player version. I suppose the problem is more on the Flash end than in Firefox... though the new Flash update works well in Chrome and Safari and IE.

You can first try to update to the latest Flash 11.3.300.262 version if you currently do not have that version.

If you can't get Flash 11.3 to work then you can try to revert to Flash 11.2.

You can download the Flash 11.2 player via this direct link:

You need to uninstall the Flash 11.3 version if you downgrade Flash.

Thanks, I already did revert to the older Flash version as an interrim solution. I'm waiting for Adobe to fix this in the most up to date version.

I have the same problem but was able to find a workaround for now. Launch Windows Task Manager (Ctrl + Shift + Esc keys). Click the Processes tab and scroll down and select the plugin-container.exe line. Right-click on it and select Set Priority --> AboveNormal and then exit. That eliminated the stuttering for me.

Was eager to try this.. Didn't fix the stuttering for me. Still horrid frame rate and crashing issues...

I have the same dang problem-it really messes with my games! Up graded to the latest flash thinking that would help.That was a joke. Really irritating.Up grade...down grade... same-o same-o. Hope some one comes up with a fix

ejusczyk: Thanks for the suggestion but unfortunately it did not work for me. Back to the old Flash player...

I'm sorry the suggestion did not work for you. It really does work for my old XP computer. One thing I didn't mention was that you have to do the plugin-container.exe priority adjustment every time after you start Firefox as it will go back to the default setting once you quit Firefox and reload it again.

worked for me, thanks.

ejusczyk's tip worked for me. For extra measure, I did the same thing with the FlashPlayerPlugin process line as well. I've discovered that setting it to "Above Normal" is the minimum setting. I set mine to "High" and videos load even better.

Reverting to a previous version of Flash did nothing, but setting the priority to "AboveNormal" works.

But that's such a pain to do everytime. Is there any other workaround? Or a way to set plugincontainer.exe to have AboveNormal priority automatically upon Firefox starting?
