I have long been a fan of PasswordMaker ( http://passwordmaker.sourceforge.net/).
So: one thing you want to make careful note of are the standard settings: The number of characters you desire, the algorithm, and the character set. I, for instance, have found that numerous sites do not allow characters outside the AZaz09 range (why, I know not). So I use a relatively constrained character set (but a longer password length). Some sites even restrict the number of characters, which is a shame, because if password generation is automatic, you might as well use 128 characters, 196 characters, whatever turns you on.
Why do you want to note all this stuff: I traveled over the holiday, and left my laptop at home; and without MY Firefox with my PasswordMaker with my settings, I was hobbled. I couldn't remember my character set, etc. So you should keep those passwords.
