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 , 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
