No worries, if you donate to "Mozilla", i.e. the Mozilla Foundation, you're unlikely to fund built-in "campaigns", "studies" or ads. You're more likely to fund sociology-style campaigns and studies that have absolutely nothing to do with Firefox (https://www.mozillafoundation.org/en/what-we-fund/), because the development is done by the corporation.

Yet when you search for "donate to firefox" you will first find one of two Mozilla Foundation donation page... Just making it possible to actually donate "to Firefox" would probably help a lot...
