Gmail Notifier
The Gmail Notifier tool released in August of 2004 by Google
is primarily a Gmail alerting tool but it also allows a user to
associate “mailto” links with Gmail. When you install Gmail
Notifier you will be given the option of installing one or
both components (this beta release runs under Windows only).
G-Mailto
A utility that automatically
associates “mailto” email links on the web
with GMail. Selecting a mailto link
will open up the GMail compose window
(from RabidQuuirrel.net)
Graham Wilmott Tool
A utility that automatically
associates “mailto” email links on the web
with GMail. Selecting a mailto link

(from GrahamWilmott.co.uk)
WebMailCompose (and) GmailCompose
Makes “mailto” links load your webmail’s compose page
and adds a Compose link to the context menu. Currently
supports GMail, Yahoo, Hotmail, Netscape, OperaMail.
Mail.com, Horde, Squirrel and one user customizable entry.
Works with the Firefox/Mozilla Suite/Netscape 7.x browser.
(I believe GmailCompose has been replace by WebMailCompose)
