FWIW - I use SPB Wallet to hold passwords etc. I normally prefer OS stuff, but made an exception in this case since it syncs with (and runs on) my Windoze More-bile phone and integrates well with Firefox. Comes with password generator, can capture and auto-fill login pages, auto cleans out clipboard if you've copy-pasted data and is a general encrypted database that stores all sorts of info.
I have no idea how well it actually does in terms of leaving traces etc, but it works nicely for me, keeping my phone, work PC and home PC synced up whilst being very convenient in terms of browser use.
