I'd really like Firefox to use my X selection buffer, or, if that's not possible then stop supporting shift+insert because the inconsistency is jarring. In a terminal I highlight then use shift+insert to paste, but when use shift+insert in Firefox it pastes my copy buffer rather than my selection buffer. So I copy something from the web, then use shift+insert in my terminal because I'm used to that now, and I paste the wrong thing in. And I highlight something in my terminal, switch to Firefox and use shift+insert to paste it, and it pastes the last thing I ctrl+c'd. If shift+insert did nothing in Firefox then I'd get used to it, but the switching back and forth is something I stub my toe on every day. Does nobody else feel this pain? Please fix it!
