No, not at all.  Bug 584678 is about a _compile_ error in a build that's newer than beta 2.

This bug has nothing to do with redirects, and everything to do with this header the server sends:

Content-Disposition: attachment; filename*=UTF-8''"Why%20Muslims%20Love%20the%20Month%20of%20Ramadan.pdf"

for the actual URL involved, which is http://public.blu.livefilestore.com/y1pedrwDaQ2cDOWPG6cI1IGdGknjycoUXcvXE25pz5MhIn3ZpWBjkImsChNe__bFrfVwMf0oupEb8jw6o_nnmLR0g/Why%20Muslims%20Love%20the%20Month%20of%20Ramadan.pdf?xdownload&psid=1

Per spec, I think our behavior is correct, but it might be worth doing quoted-string detection after doing RFC 2231 encoding conversion...

Jason, can you double-check my spec-lawyering here?
Status: UNCONFIRMED → NEW
Ever confirmed: true
Keywords: helpwanted, student-project
Summary: redirecting link is being ignored by Firefox beta 4 whereas all other browsers don't ignore it. → quoted-string content-disposition filename encoded using RFC 2231 doesn't strip the quotes from the value
And to be clear, the HTTP RFC says that the filename is either a quoted-string or a single token.  The RFC 2231 encoded filename is a single token as far as HTTP is concerned, and RFC 2231 itself says nothing about quotes being OK to remove (because things are escaped through other means in RFC 2231).  So technically, that server is saying the filename is "Why Muslims Love the Month of Ramadan.pdf" including the '"' characters.

Agreed. Unless this is really widespread I'd recommend not to add any workarounds for broken content.
