i just started using firefox for visiting just microsoft sites . after opening around 10 tabbed pages , i pressed the ctrl+shift+tab key to go to previous page .but firefox just hanged . isnt that the gesture for changing to previous page ??? why does it crash firefox . anything to do with microsoft site ? anyway i can continue firefox from where i left prior to the crash , like in opera ?? another error i get while visiting this forum is -------- phpBB : Critical Error Could not connect to the database -------- whats causing it ? another prob : in opera i use my own default colors for page viewing . black background with yellow text . and use my style/fonts/colors option from page style , yet some text are not converted to my color settings . eg. http://www.mozilla.org/support/firefox/keyboard in this link none of the "ctrl" "shift" "alt" etc are changed to my color . it stays black . what do i change to get all pages to have my color settings .
