excellent experience in chrome, but there's problem I met in firefox, when I was using vimium in websites which open each selected result in a new tab, the annoying warning that "firefox prevented this site from a pop-up window" was always there, and if I disabled the pop-up blocker from setting, with once vimium shortcut typed, the same two tabs were opened. I think it's probably a bug with vimium, because if I click the link directly instead of using vimium, all these problems above disappear.
