"Make fonts bigger in Safari. I set her up with Safari just because it's bundled with the OS and is the most straightforward, although surely Firefox and Chrome have similar options."
Being not so young anymore, I also like to set my browsers (Chrome and Firefox) to use bigger default fonts. But I find it amazing how many web sites out there have their layouts completely screwed up unless you use the default font size. When this happens, I have to hit ctrl-minus a few times for the site to look readable again. I've seen this kind of breakage on the web sites of major newspapers and other big businesses.
