This new process associated with with the recent Firefox Update to 3.6.4 is just hammering my system, with Plugin-Container.exe stealing about 60% CPU time from other applications on XP SP3. This problem only started with the upgrade that Firefox was nagging me to install and I followed the Firefox application instructions telling me to reinstall/upgrade Adobe Flash (even though I already had the most recent version, as I do with all my extensions and plugins. This version isn't ready for release. How do I roll back to the previous version of Firefox? Thanks.

== Today when I upgraded from previous to version 3.6.4, and then followed onscreen instructions to update Adobe Flash.

I am having the same problem with a similar computer setup. Norton warning comes up that Firefox plug-in container using 64% of CPU. Online Flash game no longer responds.

Works fine using Internet Explorer. I have updated Firefox and Flash plug-in but didn't help.

I am only an ordinary user and can not edit others posts but I suspect the link should be https://support.mozilla.com/en-US/questions/706123 , although that is rather a long and meandering thread, and I am not sure exactly which post the op found to be the solution.

I would comment that the Norton warning is only that something is using CPU resources.

  • You can prevent Norton flagging that particular process, but it may well then flag up something else unless the warning is disabled entirely
  • The plugin container using the resources will be running a plugin such as FlashPlayer. If you are running high resolution and high bandwidth video it may not be unexpected that it is consuming a lot of resources.

It may be worth starting your own thread if you want answers regarding your own specific problem. If you do start a new thread I suggest you try to make use of the options offered to include system information as you create the question.

It is also a good idea to check the computers specification, and compare it with the specifications

by any plugins that are used. Remembering in the case of videos that there are many variables to be considered regarding quality, resolution , codecs etc
