Windows 7 Ultimate 64-bit (6.1, Build 7600) (7600.win7_rtm.090713-1255)
Intel(R) Core(TM)2 Duo CPU     T9300  @ 2.50GHz (2 CPUs), ~2.5GHz
NVIDIA GeForce 8600M GT; Driver: 9.18.0013.3165

Actual Result:
When the user selects to play the following YouTube videos with the resolution set to max; the browser starts to use up a lot of memory. As a result a massive slow down/delay occurs when switching between tabs.

Steps to Reproduce:
1. Open up the following URLS (YouTube) videos in a separate tab:

2. Change video resolution to the max setting 
3. Switch between tabs, and observe that switching between the tabs causes a slow down (lag) in performance

I cannot reproduce this on my Razerblade laptop running Windows 8. Todd, can you check if this reproduces for you with Firefox 37 from beta.mozilla.org?
