Why do you need my address in order to process a donation? Can I donate anonymously?
We understand that your privacy is very important. We ask for a minimum amount of information required to process credit card donations, including billing address. This allows our payment processor to verify your identity, process your payment, and prevent fraudulent charges to your credit card. We keep your information private, if you have questions please refer to our Privacy Policy. If you would rather not fill in your information on our online donation form, you can mail a check.
How will my donation be used?
We're the leading open source cross-platform email and calendaring client, free for business and personal use. Your donation will help ensure it stays that way, and will support future development.
Doesn't Thunderbird earn income?
Thunderbird is maintained by the Thunderbird Community, in cooperation with Mozilla Corporation, a wholly-owned subsidiary of the Mozilla Foundation. Thunderbird derives almost no revenue from search and other non-donor sources. Thunderbird relies heavily on the generous donations of users and friends of Thunderbird.
Who donates to Thunderbird?
Anyone can donate, companies and individuals, to Thunderbird to protect the product now and in the future.
Does my donation give me access to tech support?
Anyone can access tech support by visiting the support forum. Donations are not required to receive tech support.
Can I donate bitcoin?
We are not currently accepting bitcoin.
Is my donation tax deductible?
Thunderbird donations are processed through The Mozilla Foundation, which is a California non-profit corporation exempt from United States federal income taxation under IRC 501(c)3. The Mozilla Foundation Tax ID: 20-0097189. Donations are tax deductible for United States citizens. For donors outside of the United States, please consult with your tax adviser about whether your donation is tax deductible.
In the case of some substantial gifts we may be required to report names and addresses to the IRS. Mozilla is required by law to report this information for its substantial donors and for certain in-kind gifts. These requirements would not apply to any donor donating $5,000 or less.
How do I cancel or change my recurring donation?
If you used PayPal to set up a recurring donation, you'll need to login to your PayPal account to make changes or to cancel. If you made a monthly donation using credit card, please send an email to our support team at thunderbird-donate@mozilla.org. Include the email address and name you used to make your donation and we'll try to help you within 48 hours. Do not send any other details about your credit card.
Can I donate in a currency other than United States dollars?
Yes. On our online form, use the drop down menu on the form to select any of over two dozen currencies. We are able to accept paper checks in non-USD currencies, though they are more expensive for us to process.
How can I get a receipt for U.S. tax preparation purposes?
If you give to Thunderbird through an online form you should immediately receive an emailed receipt for your donation that you can use for your U.S. tax preparation purposes. Check your spam folder if you don’t see that email arrive in your email inbox as it can sometimes be caught by spam filters. If you need an additional copy of your receipt for you for your U.S. tax preparation purposes please contact us at thunderbird-donate@mozilla.org.
Do you accept stock donations?
We are not currently accepting stock donations. Monetary donations will be much appreciated.
