Review for KDE5 Wallet password integration by D.E.
Rated 5 out of 5 stars
While KDE5 Wallet password integration works well for regular e-mail accounts in Thunderbird, it breaks IM functionality - in the accounts window (opened by "show accounts" button) "No account configured yet" displayed instead of actual list of existing and configured accounts. This was first spotted with KDE Wallet password integration for KDE4 and not fixed since.
