(Firefox :: General, defect)

You guys have apparently created a memory leak in the new version which makes it impossible to upload reasonable-sized videos to YouTube using Firefox.  In fact, it makes it impossible to do anything at all on my computer after it has been uploading for a couple of hours.  I killed every other app on my machine.  Firefox gobbled up all the VM.  I closed all but the one tab in Firefox.  The VM thrashing gets so bad that the upload process can't complete.  I couldn't even QUIT Firefox.  I had to "Force Quit" (kill) it.

Please fix this soon.  I hate to have to use another browser to do my YouTube work!  (Thanks!)

Reproducible: Always

Steps to Reproduce:
1. Upload a 1 GB video to YouTube.
2. Rinse & repeat. It won't be long until you have NO virtual memory left!
3.
Actual Results:  
Already answered:  Thrashing, couldn't run anything on computer, eventually including Firefox.  I had to kill my upload (Force-Quite Firefox) after 6 hours invested in it!

Expected Results:  
It should have released the VM it requested, and finished uploading my video!

What more can I say:
I'm running a MacBook Pro, 2.4 GHz Intel Core i5, 4 GB RAM, 1067 MHz DDR3, 350 GB internal HD, 4 TB of HDs on firewire.

P.S. I always keep 2 additional YouTube tabs in Firefox open while I work.  They are usually just sitting in the "My Videos" page when I am not using them.  I don't know if this could appreciably influence the state of Firefox, but, being better safe than sorry, I thought I should mention it.

A similar behavior has been reported for Firefox 4 on Windows in bug 647592.
