This has been happening to me recently, and it's really annoying. In my case, Firefox doesn't crash, and the other tabs remain usable. In fact, I can select the problem tab and hit Ctrl-W and avoid the problem. However, going to the same link will immediately reproduce the problem. If I close the extra window, all Firefox windows are closed without warning. The workaround is to restart Firefox, then go to the link that caused problems.
I think this has something to do with JS, because I think it only happens on pages with JS on them. -- Crash after firefox is opening a new window (when it should open the new URL in the same window/tab) https://launchpad.net/bugs/19552 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
