How can I change the default process priority for plugin-container?

  • No replies
  • 9 have this problem

I'm on Windows XP and using Firefox 16.0.2.

While browsing the web I often listen to pandora, but the music playback is always choppy or jerky. It especially occurs when scrolling pages up/down on other tabs. I saw on another question - https://support.mozilla.org/en-US/questions/930496 - that one solution is to change the plugin-container.exe priority to AboveNormal. I've done this several times and it works really well!!

I also tried changing the firefox.exe priority up and down, but this is ineffective (choppy playback problem still occurs). It is very much related to the plugin-container priority.

Please could you provide an about:config option to set the default process priority for the plugin-container. It would make a big difference for those users who have the problem. Thanks!
