Wow you wouldn’t think this would be difficult…
For mailto:
- Make sure you are logged in to Gmail and the active window is your main Gmail page (or nothing will happen).
- Copy/paste this into the address bar:
javascript:navigator.registerProtocolHandler("mailto","https://mail.google.com/mail/?extsrc=mailto&url=%s","Gmail")
- Add the javascript: to the front again if needed, because when you pasted it, Chrome probably trimmed everything before and including the colon. Then hit enter.
It also works for webcal:
- Make sure you are on your Google Calendar page (or nothing will happen).
- Copy/paste this into the address bar:
javascript:navigator.registerProtocolHandler("webcal","https://www.google.com/calendar/render?cid=%s","Google Calendar")
- Add the javascript: to the front again if it got automatically trimmed. Then hit enter.
