Stuttering flash videos on Firefox 4

more options

I just upgraded to Firefox 4 and noticed that Youtube videos (and other flash player videos) stutter. Doesn't matter if it's in 480p, 720p or 1080p, if the video is precached or not. It's not constant, but it does happen several times throughout the video and it's quite annoying.

They were playing perfectly before I upgraded to Firefox 4.

I had the same problem. Increasing browser.sessionstore.interval appears to have fixed it for me.

Hi there,

I had this problem, and here is how I solved it: some time ago I had "signed" up for the YouTube HTML5 trial.

As a result my computer had a cookie stored, and YouTube served HTML5 content.

Turns out that Firefox4 has trouble with some YouTube HTML5 videos, and it results in audio/video stutter/freeze.

Signing out of the HTML5 trial, and getting back to using Flash solved the problem.

You can check whether or not you are on that trial by going to http://www.youtube.com/html5

Configuration I am using: OSX 10.6.7, MacBookAir, Firefox4.

Update to the latest version of Flash @ http://get.adobe.com/flashplayer/

The version you're running at the moment is also a security risk. See http://www.adobe.com/support/security/advisories/apsa11-02.html

I tried setting the interval as high as 1800 seconds, and I'm still experiencing horrible stuttering in flash videos. At least one of my CPU cores is thrashing pretty badly when this happens. I'm running Snow Leopard 10.6.7 on an older Intel Core 2 Duo MacBook, 2.5 GB RAM with about 75% of my 390 GB HD partition free. Any suggestions would be very welcome!

What interval did you set the value to?
