Rated 4 out of 5 stars

Improvement: I've added this:

mapaPlus.login2 = function()
{
mapaPlus.login(false);
BrowserReload();// <=ADDED
}

Because when I set my master password: it doesn't show my login+password on the web page...
With this hack it works fine :-)

This review is for a previous version of the add-on (1.21.6).
