Multifox is an extension that allows Firefox to connect to websites using different user names. Simultaneously!

For example, if you have multiple Gmail accounts, you can open them all at the same time. Each Firefox window, managed by Multifox, accesses an account without interfering each other.

Multifox is a Grand Prize Winner of Extend Firefox 3.5! Check out some Multifox reviews: Tekzilla, How-To Geek, Lifehacker, Download Squad.

Identity Profile

Each Multifox window is flagged with a number indicating the identity profile. Logins made in windows with different numbers are isolated.

If you need to access 5 Gmail accounts you will need 5 windows with different identity profiles.

Other Features

  • Logins are preserved the same way they are in “regular” windows. Even if you close the window or quit Firefox.
  • The identity profile of each window is preserved when Firefox restores the session.
  • New windows inherit the identity profile from the window they were opened from.
  • Multifox begins from 2, because it considers 1 the “regular” Firefox identity profile.
