Comment 12 for bug 1236749

I hope this will help in resolving this issue - at lease for some. There are three possible login entries in the session menu accessible via cog to the left of the login button. Set option to "system default" instead of "gnome or classic" , extensions should now stay enabled after reboot. This has worked for me on two recent installs, including one I did earlier on today on which I am currentlly making this post. Good luck......
