From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.0.0+) Gecko/20020506 BuildID: 2002050604 When opening a link into a new tab or window, the back button history should be inherited. Reproducible: Always Steps to Reproduce: 1. Open a link in new window/tab 2. Go to newly opened window/tab 3. Back button is greyed out (no history) Actual Results: The new page opened is started as a new root to the history-line. Expected Results: The new page opened should be treated as a fork from the history-line. I think this should be expected behaviour because it makes sense to me conceptually. Sometimes I open a bunch of links to new windows from a site, and then on the final "link of interest" open it in the original window. Since only one window has the complete "back history" I have to carefully monitor which one it is to avoid closing it by accident.
