There is a problem which I tracked down to Tab utilities fixed - Version 1.5.2015.09.12.1-let-fixed. I use Windows 10.
Whenever I want to use a Pop-Up Window from Firefox (such as add keyword for search, new folder in bookmark-window), there is no content shown for this dialogue. The "Save-File-as" or "add Bookmark"-Windows work, though.
