on firefox 44.0.2 version I tried some tricks to fix the "doing nothing" issue with the addon, and I found a solution.
at first I tried uninstall and reinstall but did not fix anything. I noticed that all the settings for the addon was retained also after the uninstall.
so I uninstall, exit firefox, open Firefox\Profiles\pref.js and remove all the user_pref("extensions.UIEnhancer.*); in there.
reinstalled the addon and now it was working.
hope it helps. glad I found I way through because this addon is super useful.
