How will my donation be used?
Don’t Mozilla products, like Firefox, earn income?
Firefox is maintained by the Mozilla Corporation, a wholly-owned subsidiary of the Mozilla Foundation.

The Mozilla Foundation’s education and advocacy efforts, which span several continents and reach millions of people, are supported by philanthropic donations.
Who donates to Mozilla?

Does my donation give me access to tech support?
Anyone can access tech support for Mozilla’s products by visiting the support forum. Mozilla does not provide tech support or enhanced tech support in exchange for donation.
