Marked it 5 stars as I like it. It generally works. However, with the latest update, it seems to cause heavy CPU usage due to an unresponsive script when I have Twitter open and the Twitter tab selected. Have updated to latest KeepassXC (2.3.3), have forgotten all browsers and reconnected the database. Have removed and re-added KeePassXC-Browser - same. Removing the add-on stops the heavy CPU usage and the poor browser performance on Twitter.
