Firefox continues to load streaming videos even after the tab is closed
I'm running Windows 7 64-bit, and I've noticed that whenever I go to load a video (from Youtube, for example), and close the tab before the video finishes loading, Firefox would still be downloading that video.
I can tell because my normal ping to a local server is about 50-60ms. Then when I begin loading the video, it'll jump up to about 800+ms. I close the tab, but the ping continues at this rate. If I go to another video, begin loading that, and close it before it finishes in the same fashion, it will stack, and Firefox will be loading two videos at once (my ping will spike to 1600ms).
This is an extremely annoying issue since my internet connection is on the slow side.

Hopefully this helps. I have the same problem, except I haven't tried this solution yet. http://www.chromeboard.com/showthread.php?s=06cac3f11dbe4e21509... It seems to be BitDefender that's causing the problem...
That's interesting. However, I don't have BitDefender, so it must be something else in this case.
I have the problem too. It's not a Windows 7 issue, also Xp is affected. Any kind of download, after cancel, firefox continues the download in backgroud. confirmed by networks managers in several systems and direrent S.O and configurations.
I used NetLimiter, with plots network bandwith usage per thread. You can see how connetion is alive after close a tab. (and still downloadin)
Normally, firefox for a download creates two connections.
localhost:XX -> webserver:80
firefox-> localhost:XX
when you cancel the download, only one connection is closed, the other one (localhost:XX -> webserver:80) continues downloading.

SOLVED!
The hidden download was caused by a Firefox extension named GrabPro, included in "Orbit Downloader" boundle.
GrabPro caches all streamed media, providing a way for save it quickly. You can disable this feature unchecking the "Enable Recorder" option in its configuration dialog.
This sofware was present on all my tested systems. That was the cause of my confusion.
