What are these buttons on my title bars and how can I get rid of them?

For some reason I have started getting four new buttons in all of my windows title bars, next to the "Minimize, Maximize & Close" buttons. These give options to "Roll Window Up, Create Floating Icon, Hide to Tray, and Always on Top."

Handy, but those buttons conflict with tabs I have open. If I click a tab near the right side of the page, one of these buttons gets clicked instead. The program I'm working in disappears to the tray or to a floating icon. I've right-clicked the buttons to check for the program name or options to disable it, but neither of those options appear in the context menu.

This is driving me nuts. This isn't a Firefox add-on because it appears in most other programs too. Any help would be appreciated!
