As of the current nightly, I can't drag and drop tabs or reorder tabs in the tabs toolbar. This seems associated with a message in the Browser Console: TypeError: this.AppConstants is undefined tabbrowser.xml:4401:18 Default theme, fresh profile. Buildconfig: Built from https://hg.mozilla.org/mozilla-central/rev/82ae3b4e2215
Probably a dupe of Bug 1146193.
