"- keep reading another tab while waiting for a page to load." Oh tell me about it. That's just about dead now. I mean, wasn't the point of multi tab browsing that I could do precisely that? Now I load Google Maps on my lethargic internet connection, go do something else for ten minutes, and come back and ... it starts loading when I open. This is on Firefox. Super sad.
