Assegnate 3 su 5 stelle

Thank you for this useful add-on which fills a gap in Thunderbird security.

My suggestions:
* Please let the add-on ask for master password once when "Ask for master password at startup" option is checked. Currently it asks for it twice, which is contradictory with the purpose of the extension.

* Please add a time-out function to master password. I suppose currently there is not any extension providing this function for TB.

Thanks.
