Problem downloading with CastPost

Hey, recently found out that one might face problem downloading ZIP files that i posted in the blog using CastPost. Anyway, the solution is, if u're using IE browser, then just right-click on the link and select 'Save Target As'. If you're using Mozilla FireFox ... then, im sorry ... it seems that Mozilla FireFox dun have that option. *im using FireFox version 1.5*. Please let me know if you have any solution to this problem using FireFox browser.

Im kinda trying out Mozilla FireFox browser now... performance quite good.. just that i found some bugs with it that are not found in IE. *im not bashing Mozilla and im not a Microsoft-pro person* ;)

Peace.
