Mozilla Foundation vs Corporation
I was confused about this myself up until recently, but Firefox is NOT developed by the non-profit Mozilla Foundation! It's developed by the Mozilla Corporation, which is a for-profit entity!
If you're willing to run a browser developed by a for-profit company at all, Firefox is probably still your best bet.
