In about:config you could try setting network.prefetch-next to false.

It is obvious indeed. :-)

The number were taken from Daily usage tab in gkrelm. Before making the 
test I had purposely not accessed Internet that day (except loading the 
page with the movie certainly). Thus gkrelm only showed a couple of 
dozens of MB due to some minor local network activity, which I ignored.

I've already submitted a bug to Mozilla but was interesting to listen to 
community. If I've experienced some abnormal Firefox behaviour is not 
very likely that mine was totally unique experience.

I'd hate to switch to Google Chrome from Firefox, since the last is my 
favourite.

Sorry for asking the obvious but, if gkrellm had logged 7.345 GB
after watching the film in Chrome and 6.302 GB after watching it
in Firefox, how much had it logged immediately before that ?

Potentialy OT: Firefox downloads over 6 GB of data streaming < 1 GB movie.

[Juan R. de Silva]

Debian Jessie with Firefox 47.0.1 from Mozilla Debian Team. Firefox uses 
"automatic cache management", which is default. The problem showed up 
just recently.

Today for a test sake I streamed a movie https://archive.org/details/
SoylentGreen1973. The size of MPEG4 file is 919.8 MB. 

All apps, which potentially could use Internet, were shutdown. I'm on 
wired connection to my router, Wi-Fi disabled on laptop physically - 
switch turned off.

After movie completed I found the following in gkrellm, which monitors my 
network traffic:

Received:   6.302   GB (vs. 919.8 MB original movie size ?!!!)
Transmitted:138.43  MB
Total:  6.440   GB

Then I streamed the same movie in Google Chrome and after completed found 
this in gkrellm:

Received:   7.345-6.302 = 1.043 GB (~~ equal original movie size)
Transmitted:146.93-138.43   = 8.5   GB
Total:  7.491-6.440 = 1.051 GB

No wonder in last 10 days internet usage with my ISP rocketed up.

Anybody knows what is going on? Why streaming HTML5 video (I've not tried 
flash yet from the same source) in Firefox downloads data over 6 times 
the size of original movie? I never experienced anything similar before 
neither with Firefox nor any other browser.

Thanks.
