Rated 5 out of 5 stars

The only niggle was that my existing Firefox password database with over 200 passwords seemed to have "disappeared" which was not the case. The solution was to temporarily disable the extension then export my password database to an XML file using Password Exporter 1.2.1 (a different extension). I then re-enabled KDE Wallet Integration and was then able to successfully re-import all my Firefox passwords into KDE Wallet. Great job!
