 ## Fixed
 
 - Web UI
+  - Firefox no longer fills a saved login into the new admin password fields. It also put the
+    user name into the NTP poll interval, which marked the Time card as edited, so it kept its
+    defaults (NTP off, no server, UTC-12:00) instead of the switch's settings.
   - Accept firmware uploads regardless of the file part's MIME type, including
     `application/macbinary` sent by Chrome on macOS for `.bin` files.
