When I open FF there is no text displaying(menus, content, etc.), and most of the window is blacked out. For example... I can see the the firefox button on the top left corner, when I go to it the drop down list drops and there is no text, if I move down the drop down I hit where there is a slide out in that drop down and no text is there. So, to start in safe mode you need to go to the firefox button, and click on start in safe mode. I can't See safe mode or click on anything were safe mode should be.
