Firefox 32.0 CPU Hog Uploading to YouTube

XP Home, single core 1.3gHz CPU, uploading a MP4 to youtube consumes 100% of the cpu shared among firefox, vsmon and system. This more or less prevents the computer from browsing anything else during an upload. In fact it's so tied up that you can get Firefox (not responding) if you try.

In particular it doesn't seem to use plugin.exe (if it did before).

Anyway there was little CPU load with 31.0 and earlier.

I can't distinguish whether it's the new Firefox or a change in YouTube or a new camera, though the latter is unlikely, MP4 being MP4.

For Firefox cpu performance troubleshooting please see: Firefox uses too much memory or CPU resources - How to fix

Do you have https://www.youtube.com/html5 enabled? and does it also cause issues in a different video format?

Is there an issue with the size limit of the mp4 video? https://support.google.com/youtube/an.../71673?hl=en&ref_topic=2888648

Latest flash and java update should be checked. Another place to look for errors when you do this is in the tools > Web Developer > Web Console. Any weird errors?

This is on uploading, not playing. It's just copying my file up to YouTube. No flash would even be needed.

I have the same problem. Since FF v32.0, when I upload any type of file to any site (youtube, dropbox, mediafire, google drive, etc) while FF is uploading it uses 90-100% of the CPU. The strange thing is that without changing anything in the settings/addons/plugins, I just "downgrade" to FF v31.0 and the CPU usage while uploading is only between 10-15%, which has been the behavior since I started using FF many years ago. It's not a problem from my system, otherwise the behavior would be the same with any version. It's also not a problem from the website(s), since it happens with all of them when uploading the file. The behavior only happens when uploading a file, not when viewing a file on youtube or even downloading any file from any website. What could be causing FF v32.0 and onwards to use the CPU at it's max.?
