This is part of our year end donation campaign. It is shown to all Firefox users who have the default "about:home" homepage set. It doesn't have a way to tell that you have already donated unfortunately. You can either ignore it, or change your home page until after the first of the year.

Sorry about the annoyance and thanks for the donation!

I notice that every time I open my Firefox I still get a request to donate. I donated following their online form and have a Paypal receipt for it. Should the request go away or is it now standard on opening Firefox? Most other organisations e g Wikipedia don't keep reminding you after you've donated.

Thanks for the info. No worries about the page. I was concerned that the donation hadn't gone through. All good. :-)
