in ff 36 when siging out of a website another tab opens instead of closing the current tab
When I updated to V.36 this action started . With certain websites when I try to sign out instead of the webpage closing, a new tab opens and the home page of the same website opens. The original tab is still open with my account information still logged on and the only way to log off is to click the X on the Tab. The problem disappears when I uninstalled Tab Mix Plus. This issue did not happen in the earlier version of FF and I always used Tab Mix Plus with the previous versions.

Instead of closing the tab where you logged out, what if you reload it using Command+r (or the reload button in the address bar). Does it show that you are properly logged out at that point?
My guess is that the site is sending a redirect after logout and somehow that is getting diverted to a new tab for some reason instead of loading in the same tab. I don't have any good guess as to why that would happen. You might pose this question on the Tab Mix Plus support forum to see whether it's a setting you can change or a compatibility issue with Fx36:
