I would also like to point out that I would absolutely pay $5/month via something like a Patreon which funded an organized group of security minded devs to work on Firefox security issues.
I use Firefox, but only because of "browser diversification" and privacy. Other options are worse not because Firefox is a superior product. It's sad really.
But I feel like I would be doing a disservice to myself, and my employers, by continuing to use a less secure browser, just because I’m religious about Mozilla.
