Steps to reproduce:

I uploaded big video file (full hd) with size of 1.7GB on Facebook. After upload, I opened it and tried to TAG people on it but internet was gone and nothing was working on Firefox browser. 
then I did the same with Chrome browser, everything went well and I tagged some of my friends. 
After that I tried again with Firefox and Internet crashed again on Firefox browser. 
then I did a video that shows this internet crash thing and you can see what happened.

this is the Dropbox link of the file: 
https://dl.dropboxusercontent.com/u/73043365/firefox%20internet%20crash.mp4



Actual results:

Internet was gone, Internet was crashed on Firefox browser and CPU load of firefox.exe was 30-35%. even after I closed all the tabs it was not going down and has not gone down until I closed Firefox browser itself.
it's not my computer issue. my computer specs are good: CPU is i5 2500k, MoBo is p8z77vl-x and GPU is Evga GTX280 and RAM is 8GB.


Expected results:

firefox should have let me tag people without any crash of internet connection.

This video isn't recovering from seeking. We're seeing high CPU usage and the network connection seems to stop working. I don't really understand what is going on here.

Michael - does your hard drive light come on when this happens?

Anthony - no, it blinks as usual, nothing special. do you want specifics of video or something?

Any idea what could be going on here, P?

it sounds like the socket thread is stuck in a loop of some kind.. do you think this can be repro'd with any big file, or would we need to share that one?
