GA uses first-party cookies so Firefox does not block the data. Only third-party cookies mentioned here: https://www.mozilla.org/en-US/firefox/browsers/compare/chrom...

I just double-checked my real-time analytics and looked back in the last 30 days to double-check. It's all coming through GA while I am in Firefox or other users are using Firefox.

The first vs. third-party cookies are confusing as hell.
