It's not the font that makes it faster to read, really, it's that it's in text mode. The Courier is easy to read because it doesn't use proportional spacing, has clear serifs and draws well, which also makes it fast to read, but the main deal is that without HTML and images, it just draws a lot faster. My point in mentioning it, however, was to point out that it's local settings that determine how your message will be seen, not what you see on your side. If the reading program doesn't find Georgia installed on the local system, it'll look either for the next font by alphabet or, if a family is specified, the first on on the list that it finds installed will come up.

Thanks bbbluz. Have tried all on the link you provided. Did improve a couple of problems, but the darned "Bookmarks", toolbar and tabs remain teenie, tiny and barely readable. I'm using FF 38.0.1 and OS X Yosemite 10.10.3.
