I have version 29.0.1 and frequently the top right three boxes (min, max, quit) are missing. How should I do?

Since the installation of version 29, I had this problem where the three boxes are missing. It happens sometimes that I start FireFox. I can right-click in the min, max or closing of FireFox and area. I never had the problem before. I have an i7 processor and on Windows 7.

The boxes are not visible (i.e., they show a ToolTip if you hover and work if the click in this area) or whatever should not happen at all?

You can check the problems caused by a corrupt localstore.rdf file.

You can check for problems with preferences.

Delete a possible user.js file and files numbered prefs-# .js and rename (or delete) the file prefs.js to reset all the prefs by default, including the prefs set via user.js and pref which is no longer supported in the current version of Firefox.
