It will be impossible for me fix something that I can't reproduce. I'll need more information than "it doesn't work". Please submit detailed information about the problem including messages from browser console at provided support website (or email) Thank you.
extends Thunderbird, Seamonkey and Pale Moon build-in password manager with timout, automatic lock and other useful features. Before you start complaining this extension is not compatible with Firefox 57+, learn WHY Mozilla ruined own product by removing XUL add-ons and replacing it with crippled-down API.
This review is for a previous version of the add-on (1.29.2).
There is nothing to update, Firefox Quantum doesn't have the needed capability for this addon to exist. It still works with Waterfox and Palemoon (and other Firefox - based browsers that support "legacy" extensions)
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.
