When I hit a bookmark or tab or 'enter' button the screen flashes black briefly. I will also lose the bar on the bottom and the red 'x' on the top right hand corner.
This has just started happening. The screen doesn't stay black it flashes black behind the screen. Also, when I do anything with the File, Edit, History, Bookmark, Tools, Help functions, the bottom bar appears again.
This happened
Every time Firefox opened
== Last night after installing up-dates for firefox and mozilla
