Starting from Firefox 27, video stuttering & 100% CPU usage
I'm running Windows XP SP3 with 2 GB of RAM and 3 Ghz CPU.
Starting from firefox 27 and now with v28 too, I noticed that the average usage of CPU is higher that before, and this is particularly noticeable when browsing YouTube and other video content based sites, where the CPU reaches a constant 100% and the video stutters. I have the latest version of Flash Player.
So at the moment I remain with v26, with which this problem does not exist. There is a fix for this, or should I remain with v26?

Are you still having these problems ?
You say it is not video related.
Have you tried in Firefox's safemode and with all plugins disabled ?
- Diagnose Firefox issues using Troubleshoot Mode
- Disable or remove Add-ons_how-to-disable-plugins
Does it then still stay at 100% after two minutes browsing ?
That must make Firefox very difficult to use.

Thank you for your support Waka_Flocka_Flame! I can add that the problem is not only video related. After two minutes of normal borwsing, the CPU reaches 100% and stays at 100%. However, here are the information you requested, and again, thank you for your support!

That must make Firefox very difficult to use.
I found the culprit. It's DownloadHelper. Uninstalled and everything works again. Sorry for the inconvenience, it was not a Firefox issue.
john99, thanks for putting me in the right way for troubleshooting this problem (now solved).
In my personal setup, DownloadHelper causes the issues starting from firefox v27 and above.
