A new experimental version is available at http://keefox.org/download/experimental-version. There are a couple of important bug fixes including one where some other parts of Firefox stopped working when KeeFox was installed so I recommend all users of 0.8.12-14 should upgrade. Users of 0.8.10 should not be affected by this bug.
The other improvements since 0.8.12 are:
- Improved password field matching
- HTTP Auth dialogs now respect global and site-specific “offer to save passwords” settings
