I am trying to make a pure javascript app capable of uploading certain files to dropbox. However I have hit upon a roadblock . Apparently on firefox 3.6 to be able to make a cross origin POST request . Firefox first sends the Access Control headers via the option method.

However it seems that dropbox does not support the OPTIONS request for the url

and thus gives a 405 error but without the auth info on my POST request i get a 403 error. Does this mean its not possible to do what I am trying to do on firefox 3.6
