With Safari, when I type, it appears to be 4 or 5 point type. Not good. I won't use Firefox, as Safari works with the ipad and ipod to update my bookmarks and such using my wifi and keeps all my devices in sync with each other.
I can go to Firefox or Chrome if I **have to*** for troubleshooting or if something really won't work other wise, but ....... Safari is really where I want things to work because all my devices work with each other that way.
