You might want to look at other KeePass extensions:
- KeeForm (supports IE & FF) -- I've used this and found it works fine for Firefox. (I rarely use IE)
Note: I haven't seen any updates to this one for the last month- PassIFox / PassIChrome -- recently developed set of plugins for Firefox (4 only) and Chrome.
Note: haven't tried this one yet since I'm still using FF 3.6.17
Further notes:
- Keeform for FF requires the plugin
- PassIFox & PassIChrome require the plugin
