Password not encrypted in Firefox.

[webapp]

I figured out how to run a script recorded on IE to run on Firefox.
The script runs only for few statement like it opens the web application, logs in,
enters id ,does not recognize password and then fails, throwing an error that the object is not in the object repository. But when I run the same script without making any changes, it runs fine on IE-6.
I tried adding the object into object repository but still throws same error.

Any help on this is greatly appreciated.

Thanks.
