Hi David, did you already set up an email mask in Firefox Relay, or are you getting a page telling you about Firefox Relay that you want to stop seeing? If a page repeatedly appears at startup, it might have been added to your Home Page setting. Please see the following article for how to check on that: [[How to set the home page]]. With the Custom URLs setting, you can have multiple tabs open -- the different addresses will be separated by a | character (can be hard to see).
