Join Mozilla Support FAQ

Why should I become an official Mozilla supporter?

We're the proud makers of Firefox, but that's not all. Mozilla is a global non-profit, building communities and giving people tools to control their online lives. We are about enriching people's lives instead of benefiting shareholders. We believe a better Web means a happier future for all of us—and we need your support to build it.

We don't have shareholders. Or a fancy stock abbreviation. We answer only to you. Join Mozilla here and start protecting the Web today!

As a supporter, you'll have a backstage pass to the work our community does every day -- along with plenty of opportunities to take part! You'll receive regular content tailored for you, be among the first to learn about new programs and have opportunities to meet others all over the world who love Mozilla and support the web.

For how long will I be an official supporter?

When you join Mozilla you will become an official supporter for a 12-month period from the date you donated. You may also receive other fundraising requests at various points in time, but that does not affect your status as an official supporter. Your support will not auto-renew.

My card won't print!

If you weren't able to print your card during the sign-up process, please drop us a line at askjoin@mozilla.org and we will be happy to help.

Can I change my t-shirt size?

Pressed the wrong button during check out? Happens all the time. Drop us a line at askjoin@mozilla.org and we will be glad to help you get the size of shirt that you want.

Where does my donation go?

Supporter funds go to support Mozilla's work protecting the web and creating a generation of webmakers.

I'm receiving a payment error. Can you help?

We use Paypal as our payment processor. If you're experiencing a payment error, check out the help section on their website: https://www.paypal.com/cgi-bin/helpweb?cmd=_help. They even have virtual live support. If that doesn't work, please email us at askjoin@mozilla.org.

How long will it take for my t-shirt to get to me?

Your t-shirt should arrive within three to six weeks from the date you ordered it.
