Safari Extension Unresponsive; App Slow Performance

• In Safari, the 1PW extension often becomes unresponsive. Clicking the 1PW widget in the username/password fields results in nothing. Quitting Safari and relaunching it restores functionality temporarily until the extension fails again minutes later.
  
  
• The standalone 1PW App is slow to launch. Once it launches, it takes several seconds to load the list of items in the view. The search function in the app is especially slow. The app becomes unresponsive for several seconds after the search term is entered until the results appear. Overall the app feels laggy and sluggish, much more so than a year ago, and much more than other apps on this Mac.
