I'd guess only a minority. However, we should also remember that Mozilla's main funder is... Google/Alphabet, via a royalty deal for having Google be the default search engine. See, e.g., here: https://www.bloomberg.com/news/newsletters/2023-05-05/why-google-keeps-paying-mozilla-s-firefox-even-as-chrome-dominates https://www.bloomberg.com/news/newsletters/2023-05-05/why-go... And while the royalties arrangement is not that old, Google was a main funder before that happened as well. FYI.
