'm experiencing the high CPU utilization when FireFox is running that has been reported in other posts. I believe the problem is the result of an interaction between multiple products. Here is my trouble shooting approach. I disabled Adobe Flash plugin. CPU utilization dropped from 70%+ CPU (60% of which was System CPU) back to < 10% CPU. I reenabled Adobe Flash and opened FireFox. CPU was again 70%+. I closed all tabs that had Flash content. After a few seconds CPU went back to <10%. I opened Facebook and CPU went to 50+% CPU, most of which was System. I opened www.wral.com and CPU increased to 70%+. As I open additional flash content pages the CPU continues to increase. Other events that may be associated with this problem were: 1. An upgrade to Adobe Flash which also resulted in periodic Flash crashes. 2. An unwanted installation of McAfee Security Scan that came with a scam virus message. Online research suggested running Malware Bytes. 3. Installation of Malware Bytes 4. Removal of McAfee Security Scan The CPU issue appeared sometime during this process but I can't associate with an exact event. My conclusion is that the problem may be due to an interaction of my Antivirus software with flash content appearing in FireFox. Running: Windows 8.1 Firefox 36.0 Adobe Flash 16 NPAPI Trial Copy of Malware Bytes 2.0.4.1028 McAfee is at latest release My next step will be to deactivate Malware Bytes. After that I will uninstall and reinstall Flash. Looking for any additional ideas and a sanity check on my conclusions and next steps.

Since there was such a drop it seems like hardware acceleration in flash is taking resources. I can suggest to try to disable this to also see if there is a difference after reinstalling.

Some problems with Flash video playback can be resolved by disabling hardware acceleration in your Flash Player settings. (See this article for more information on using the Flash plugin in Firefox).

To disable hardware acceleration in Flash Player:

  1. Go to this Adobe Flash Player Help page.
  2. Right-click on the Flash Player logo on that page.
  3. Click on Settings in the context menu. The Adobe Flash Player Settings screen will open.
  4. Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel.

  5. Remove the check mark from Enable hardware acceleration.
  6. Click Close to close the Adobe Flash Player Settings Window.
  7. Restart Firefox.

This Flash Player Help - Display Settings page has more information on Flash Player hardware acceleration, if you're interested.
