If you are using Google Calendar regularly you might find this little Firefox tip interesting. It is possible to display your current and upcoming events that you added to Google Calendar in the Firefox sidebar. This is actually pretty easy to accomplish.
What you need to do is add the mobile version of Google Calendar to your bookmarks, right-click the bookmark, select properties from the menu and check the “Load this bookmark in the sidebar” option.
