NotSharingMy.Info Anonymize email extension
Whenever a website asks you for your email address and you don't want to supply the real one, use this extension to substitute it with an anonymous alias. Just type your real email into the form, but before submitting, click the "Anonymize email" icon in your toolbar and it will be replaced with an anonymous alias.
All mail sent to the alias address will be remailed to your primary one. You can terminate the alias at any time at http://NotSharingMy.Info
