Steps to reproduce the problem:
1. Have a lot of tabs open (normal)
2. Go to a hotel or somewhere else with slow internet
3. Open your browser that has a lot of tabs open and feel the pain as they all try to reload

What is the expected behavior?
Start loading the content from the first viewable tab. If that content is loading extremely slowly, don't load the rest of the tabs until they're selected/in focus.

What went wrong?
If I open my browser at a hotel to quickly check a map or an email, after having the browser open at home/at work and I've got a lot of tabs open, it will take a long time before I'm able to "quicly" check a map or an email. It would be ideal if the background tabs weren't trying to load on such a slow connection.

Did this work before? No
