Stop Chrome loading videos in background tabs?
Until Chrome comes up with that function like FF, the closest you can get to it is to Disable lots of bandwidth and storage consuming apps.

That can be done here:



Also go to your chrome://plugins/

and disable all Plugins you do not want.

That will not stop the background loading of the page but will limit the what, and you can still use them at your desire (it will ask you).

And it looks like this example of not loading some advertisement at the top of a page.
