Does not actually send the page, just a link.

This works but I hate the way it always displays a popup window. The addon called MailTo does the same without this nonsense.

It is very frustrating that the email created to send the link does not include one's email signature. The old add-on I used for this purpose was seamless. This creates an empty window into which the link is inserted, with no identifying signature, which I hate. You can add the signature manually in Outlook, but it's very time consuming. Wish this could be fixed. Seems pretty basic.

Offers no choice between different email options (like e.g. Gmail and desktop mail client). Opens a new tab with a "mailto:" link which then opens the default mail program. However, the mailto tab stays open and needs to be closed manually.

I am using this addon with Firefox 47 and Yahoo Webmail.
Works perfect.
On another machine with Windows 10 and FF51, when I
try to install this addon, FF won't let me, telling me
the addon is corrupt. Tried disabling signature check in about:config, still doesn't download
