How do I email any web page?

[gfmetz6236]

I use a MAC desktop with Yosemite using Yahoo Mail and Safari (or Firefox). Lately, when I use Clickability's EMAIL THIS or the drop down FILE menu on Safari or Firefox, the down load does not often do anything. When it does, the page only shows "can't be opened because it is from an unidentified developer." I can't understand why it no longer works like it used to. Any suggestions or comments would be appreciated. Thanks!

You might need to associate FireFox with an E-mail client in the Firefox options. Should be in options | Applications.

Or just copy the URL and open your E-mail client, paste and send.
