Using Vista x64 hm prem. My FF & TB profiles & bookmarks were created under the default Administrator acct in Vista (custom profiles - not "Default"). Trying to use same custom profile / bookmarks if login under a standard Vista user acct.

When try to use Profile Mgr to create new profile under a standard user acct in Vista (not Administrator), & browse to profile location to select existing custom profile (per several Mozilla KBs), it's not visible - but "Default profile is."

Read several Mozilla KBs on using existing FF or TB profiles when creating new acct under another (Windows) user acct. Instructions are simple, but KBs may not address requirements or problems sharing profiles in Vista x64. KBs say should be no problem sharing same profile between users, but maybe not in Vista x64?

I have "show hidden files / folders" checked under the Administrator & std user acct. When logged in under std user acct & browse to the profile location, only default location is visible. It's not that the custom profile is shown, but access is denied - it just isn't shown in Explorer.

Tried everything can think of, Re: from w/in the admin acct, giving permissions / sharing the Mozilla appdata folder w/ a standard user acct. All the security features of Vista x64 are fine, but some are so complex I'm sure many users turn off some when possible.

Tried this for TB - same problem. Maybe I missed an article w/ instructions on sharing profiles in Vista x64, or just need to change secret setting(s)? No help from Mozilla forum.

Thanks.
