This is a simple Safari Extension that adds two menu items to the context menu. To use, install, then right click (control click on a one-button Mac mouse) on any page. You should see two menu items:
- Gmail
- Gmail (Full URL)
Each of these opens a new Safari tab or window set up to compose an email. The subject is the the page title. The body is the URL of the page. If any text is selected on the page, it is included in the body.
Because it's a Gmail composition window, Gmail address completion works as usual.
The Gmail menu item simplifies the URL by removing parameters and simplifying YouTube links. The Gmail (Full URL) menu item includes the full page URL. Otherwise the two menu items function identically.
First download the Safari extension package. Then double click the resulting file to install it.
