This simple add-on has only one functionality: it opens links in a new active tab on Shift+LeftClick, not in a new active window.
This version works with SeaMonkey and FireFox, but browser must be restarted after installation/uninstallation. You can use https://addons.mozilla.org/ru/firefox/addon/shiftleftclick-opens-links-in-/ for Firesfox, that doesn't need restarting.
