If I save a username and password combination in firefox on my desktop using the full, desktop version of a website (for example,, and then sync that username/password combo to firefox on my Nexus One, firefox on Android isn't clever enough to know that it can use that saved password if it is redirected to the mobile version of the same site (e.g.,

The upshot is that on many websites, the only way to have firefox on android use my synced passwords is to try to get to the full, non-mobile version of the site, and on some sites (esp. gmail/google reader), this is impossible without somehow changing the user agent.

Firefox's password manager splits sites based on their subdomain. and could be two different servers with different owners. It is not safe to assume that passwords can be shared between such sites.

MConner does this sound like something Sync would like to address?

I can't reproduce this. 09/02 Nightly.
