TargetKiller автор NumeriusNegidius

This extension is for us who are tired of websites haphazardly opening links in new tabs - breaking your expectations, breaking your back button, and flooding your tab bar.

This add-on removes all target attributes from all links in all webpages, except in child frames. It doesn't only remove _blank and _new, but all custom ones as well. So please beware, this add-on might break some websites!
