This Chrome/Iron extension is inspired by the excellent Firefox extension - BarTab, although it's much less sophisticated and powerful.
I didn't publish it on Web Store, because I don't have a developer account and don't want to pay entry fee to publish a free extension.
It works for 10 secs on Chrome/Iron start, blocking tabs that are not active from any web requests.
After those 10 seconds the web traffic is not blocked anymore and the extension only monitors the tabs that were previously blocked to reload them when they are activated.
