tried it, and this doesn't help.

still getting message "Sorry, Bad Request. Your browser sent a request that this server could not understand.

Size of a request header field exceeds server limit."

and the cookie that message shows is not in my cookie list.

also, your reply doesn't answer the main question - when will firefox offer an upgrade for mac ox 10.4.11 users? the sites i'm having problems with say i need to upgrade to firefox 4, but firefox 4 doesn't support os 10.4.11

not cool!

If clearing the cookies doesn't help then it is possible that the file cookies.sqlite that stores the cookies is corrupted.

Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete cookies.sqlite-journal and cookies.txt, if they exist, in the Firefox Profile Folder in case the file cookies.sqlite got corrupted.
