alt Hacker NewsI'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"
I developed and tested my personal site on Firefox. If I were a professional web developer, I'd work just like you do.
But let's not kid ourselves. We're an absolute minority. For every one of us, there are hundreds, thousands of developers who literally do not give a shit so long as their paychecks hit their accounts. Actually they're likely to write Firefox off as some irrelevant niche market the company can afford to lose because it's less work for them if they do.
