I actually hit this today during testing as well and I filed https://github.com/mozilla/fxa-content-server/issues/1053 I'm guessing Mailinator just strips the blue background from the Verify button, making the link white-on-white.
I also saw some green link text (on blue background) on guerrillamail.com, but didn't get too deep into the source to see if they're explicitly setting a/href colors or not. I'm guessing it may be something on their end considering their love of green links elsewhere as well as the green-tinted "Mozilla Support" link. -peter ----- Original Message ----- From: "Edwin Wong" <[email protected]> To: "Aaron Train" <[email protected]> Cc: [email protected], [email protected], [email protected] Sent: Friday, May 2, 2014 1:25:34 PM Subject: Re: [services-qa] Regression: Verify link not visible in Mailinator it looks like the color of the button is inverted.
