Hmm, in principle Firefox could support native encryption, where you
add the key to Firefox directly before even visiting the website.
Being a bit careful about frames and/or javascript should give you a
secure solution. The major issue then is, if security matters to you,
why do you want to access these files from the web? Are you sitting
down on an untrusted computer and just blindy entering your encryption

Still, adding support for securely encrypted files as a cross browser
standard seems like a fundamentally cool thing to do.
