hypercal 作者： larskreuz

hypercal is a self-hosted calendar. This extension brings it into Firefox.

Features:

• Toolbar button: today and the next week. The badge counts down to your next event.
• Sidebar: the same agenda, open beside whatever you are reading (Alt+Shift+Y).
• Quick add: type "fri 14:00 standup" in the popup, the sidebar, or the address bar after the keyword "cal".
• Join: a Join button on events with a Zoom, Meet, Teams, Jitsi, Webex or similar link. Alt+Shift+J opens the one that is on now or starts within 15 minutes.
• .ics links: right-click to import the events, or to subscribe to the feed.
• Selected text: right-click an invitation or booking confirmation to open a new event in hypercal, filled in with the date, time and title it names. Nothing is saved until you save it.
• Reminders: your hypercal reminders as Firefox notifications.

It works on Firefox 140 or later, and on Firefox for Android 142 or later (everything except the sidebar).

You need your own hypercal server. An admin turns on browser extension access, you create an app password, and you enter the server address and the password in the extension's settings. Firefox then asks for permission to reach that one server.

The extension talks only to your hypercal server. It has no analytics and no telemetry.
