Glance от Marco Martorana

Glance brings your Google Calendar to the Firefox toolbar.

At a glance: click the icon to see all of today's events — all-day events at the top, timed events in a timeline view.

Call notifications: get desktop notifications before upcoming video calls, with configurable lead time and reminder count. Supports Google Meet, Zoom, Microsoft Teams, Cisco Webex, GoToMeeting, Jitsi, Whereby, BlueJeans, and
Amazon Chime.

One-click join: jump directly into a call from the popup or from the notification itself.

Multi-account: connect multiple Google accounts and see all events merged in a single view.

Badge: the toolbar icon shows how many calls are starting within the next 15 minutes.

All data stays in your browser. No telemetry, no tracking, no third-party data sharing.
