How do the add-ons work?
ScheduleOnce Add-ons use the common Greasemonkey framework in order to add a small JavaScript code to your Google Calendar or Gmail page. This code only presents the ScheduleOnce control in the page, making it easier for you to access the New Meeting and Replies pages. The add-on does not affect any other part of the page or other internet sites and does not change your browser preferences in any way. The Firefox Extension uses the Mozilla standard API to integrate with the Firefox browser. The Chrome Extension uses the Google standard API to integrate with the Chrome browser. Our code is open and guaranteed to be spyware free.
