Great add-on. The browser finally behaves as it should. There is a small inconvenience since update to FF 24.0. Now when I close the window with one single New tab, the "This is embarrassing" message is displayed on start up telling FF was not able to restore previous session.
@ypeels Thanks for your reply. You are right, described bug is reproducible even in Safe Mode. FF 26 will fix it, hopefully.

이 검토는 현재 부가 기능의 이전 (0.0.5.1-signed.1-signed) 버전에 대한 것입니다. 

Thank you for your kind words! Passing the buck a bit, I'm guessing this is an upstream Firefox bug <https://bugzilla.mozilla.org/show_bug.cgi?id=853779> rearing its head... If my guess is right, you should be able to reproduce the behavior even in Safe Mode, using Ctrl+W (or Ctrl+Shift+W) instead of the middle-click. Let me know how things go!
