After a system reboot this morning, the scrollbar is unclickable (wheel based scrolling works). So is everything to the right of the address bar on that toolbar in fullscreen mode (in non-fullscreen mode, the buttons for bookmarks and add ons work, the hamburger menu does not). So are the minimize, maximize, and exit buttons on the window in full screen mode (in non-fullscreen mode, the minimize and maximize work, exit does not). Whatever is the right most tab in my list cannot be clicked. Right clicking any of these things brings up a menu with a single option- copy. The app is unusable in this state.

I have tried restarting in safe mode, this didn't fix anything. The only addons I have are noscript and adblock+.
