After installing Firefox update 22.0 the cursor started blinking when moving around in Firefox windows. No problem in other programs.
My cursor is unstable blinking in the Firefox window after installing update 22.0 . The problem disappears after through Windows System Restore the update is being undone. So it is directly caused by the update. I work with Windows 7 Home premium, Service pack 1, 64 bit operating system on a Toshiba Ultrabook. No problem whatever sofar.
