User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6 Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6 I think it would be great if Firefox allowed Mac OS X users to choose between using the Firefox password storage or Keychain. Most of the other browsers on Mac OS X already support this and I think it is a glaring omission in Firefox's feature set, especially if one is to switch from another browser on the platform.
