I use GitHub - marius-wieschollek/passwords-webextension: The official browser extension for the Passwords app for Nextcloud. with Firefox. Sometimes I make a change in Nextcloud Passwords and it seems to take a while to show up in the browser extension. How often does the extension sync? Is there a way to trigger a re-sync?
The extension syncs every 15 minutes. You can trigger a manual sync by opening the extension popup, going to the browse tab, hovering over (or clicking) the account you want to sync and then clicking the reload icon.
