The author of the “Whitehart”:https://addons.update.mozilla.org/themes/moreinfo.php?application=firefox&version=1.0&os=Windows&id=364 Firefox theme has written a Beginner’s Guide to Firefox which covers everything from what exactly Firefox is, to what themes and extensions are and where to find help if you have questions. Send it around to your non-tech savvy friends after you convince them to switch, so they’ll have a point of reference for their questions.
