Firefoc 30.0.5 on Wint Pro. Sometimes, when opening a web page the normally blue (theme) menu bars at the top of the firefox page turn plain buff, and the four small icons (minimize, resize, maximise, close) vanish (black bar only). Problem persists after closing ans restarting firefox. Remedy please

Are you running Firefox in (permanent) Private Browsing mode (never remember history)?

You could be experiencing bug 1166066 that happens when you are running Firefox in Private Browsing mode and you open links in a new window.

Possible workarounds: 

(1) use Options/Preferences > General: "Open new windows in a new tab instead"
(2) Shift+click links to open in a new window with the standard features or use the right-click context menu.

You can modify dom.disable_window_open_feature prefs and change their value to true to prevent a website from disabling toolbars and scroll bars in a pop-up window

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
