Ever sense I have upgraded to firefox 6 it is a challenge to browse the internet. the entire screen and action/tab menu bars all flash black and when I scroll the whole screen flashes black or just stays solid black and i cant see anything. Also when ever I go to my bookmarks as I scroll down the list it high lights them all black as well. the only way I can seam to use this browser at all is to restart it in safe mode then I am able to navigate but the bookmark problem still is there.
