I'm doing as much to keep Firefox alive as anybody.
Wherever I've worked as a dev in a decade I've always developed Firefox-first and let the testers turn up Chrome issues. So the products that I am involved with just work with Firefox all the time.
I know there are a lot of people like me, people who are passionate and engaged with technology but have problems with "big tech" and if they turn people like me away than it really will be a "niche browser that nobody tests"
