while reading my yahoo mail with Firefox I inadverdantly clicked the browser and the print got smaller. I clicked again and it got tiny. I don't know where my cursor was pointed. I can access my Verizon Yahoo with Firefox as a different user. I tried changing the font using Yahoo options, but nothing happens. I'm a neophyte computer user so I'm at a complete loss and would be thankful if one of Firefox's sophisticated users would help me. I'm using Windows XP Thank you. Wilkie
