twice in the past few weeks the font size on my email has changed smaller. The first time it went from 12 pt type to maybe 10 pt type. Last night while I was chatting on Yahoo with our daughter, it went down to maybe 2 pt type. I couldn't find a way to change it back. This morning I opened up the computer to try to work on it again and the font size was maybe 1/2 pt type. The words look like little squiggles on the page. Both my email addresses on Yahoo have reacted the same but the ads to the right of the email on the mail page remain the same size. If I open up another window, and say go to foodtv.com, everything is normal size. I have opened up Safari and gone to my email and everything is normal szie so the problem is the Mozilla. I have also called ATT and gotten help and they couldn't help as it's definitely a Mozilla problem.
