User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0 Build ID: 20141110004002 Steps to reproduce: I've installed newest Firefox developer edition and setup my firefox sync. On my normal firefox installation I'm using it quiet frequently and it just works. But in Firefox developer edition I can't sync anything. The funny part is that everything I add to the developer edition is synced back to my normal firefox edition but not the other way around. Actual results: Basically it doesn't sync my bookmarks, addons etc. with my normal installation but if I add a bookmark to developer edition it is synced back to my normal edition but as said not the other way around. Expected results: It should sync :)

Same here. Arch GNU/Linux 35.0a2 (2014-11-11) This bug is quite similar https://bugzilla.mozilla.org/show_bug.cgi?id=1096343
