Why would middle click not open tabs? You middle click a link to open it in a new tab, you middle click a text box to paste into it. Neither interfere with the other. On windows, you can middle click anywhere on the page (except links, ofc) to go into a scrolling mode where dragging your mouse around changes the scrolling direction. I don't think many people use that feature, but it's there, and doesn't work on linux.
