YES, I'm not the only one who uses this! As a compulsive tab-opener (I really gotta work on this...) and also a cellular hotspot user, both Safari and Chrome eat up, like, a gigabyte of traffic as soon as I open them. Firefox behaves much more reasonably, but until recently it's been very slow with 50+ tabs. I'm glad to hear this use case is (apparently) getting some close attention!
