HTTPS Everywhere "Yahoo! Mail" rule breaks Yahoo! Mail
I had to disable the "Yahoo! Mail" rule in my HTTPS Everywhere plugin (version 1.0.1) in order to sign in to Yahoo Mail today. With the rule active, clicking the "Sign In" button on mail.yahoo.com did nothing when I entered a correct username and password; the page responded normally when I entered an incorrect username.
