[Bug 1290388] [NEW] Insane memory leak loading break.com

[Ken Sharp]

Public bug reported:

I have seen that this occurs around 50% of the time and I have only seen
it on the one website: break.com.

Load break.com and Firefox immediately uses 100% of RAM and swap.
Obviously the disk goes insane and everything slows down. The only
solution is to kill that tab and try loading it again. Works fine on
Chrome.
