LastPass Login Fails [$105 awarded]

[KroniK907]

When trying to login at https://www.bountysource.com/signin using the Lastpass Firefox plugin with the "AutoFill" option, the login fails. If I manually enter or copy paste my email address and password it works fine.
I noticed when I did the AutoFill I did not get the "Found!" next to the email field. For some reason, unless I physically type in the email field it seems to not recognize the text in the field.

The $105 bounty on this issue has been claimed at Bountysource.
