Последняя версия крашит Файрфокс. Установил 1.28.2

The latest version causes a crash of Firefox. Use 1.28.2

This review is for a previous version of the add-on (1.29.2). 

If it's crashing Firefox when show prompt on startup is enabled, try wait a few seconds before entering password. It's an issue in Firefox itself, when initialization interrupted with a modal window. I'm trying find a solution for that, so far no luck.
