Do you have any add-ons installed? Can you reproduce with a clean profile? On the profile where this is broken, if you do the following:

- open about:config
- search for "devtools.chrome.enabled"
- switch it to true by double-clicking that line
- hit ctrl-shift-j to open the browser console
- evaluate: CustomizableUI.getWidgetIdsInArea("TabsToolbar")

what is the output?

This feels like bug 1370791.

Without more details this shouldn't be a p1. I'll check on bug 1370791 though.
