Firefox extension simplifies e-mailing on Facebook
User e-mail addresses on Facebook have come a long way. For years, Facebook converted them into a static image to keep potential spammers and data thieves at bay. As a result, it made copying them a serious pain, as you'd need to have whatever e-mail tool you were using in one window, and that user's profile in another.
Earlier this month, Facebook changed it to plain text, which lets you copy and paste the address instead.
If you're too lazy to do that, or just find yourself doing it several times a week, you could save yourself some trouble by installing Facebook E-mail Links, a new Firefox extension that automatically converts these links into a mailto: URL. That means the next time you click on someone's e-mail address, it'll open up in whatever local or Web-based e-mail tool you use.
