Who is this person?

That would be JR Conlin, national treasure. Worked with him on YDN in 2007 and Netflix in 2009; veterans of the Netflix API team will never forget his hack day entry, which was "Mac and Me" playing on a toaster oven.

What is he notable for in the context of Mozilla?

Maybe read the blog post? Crazy suggestion, I know.

Skimmed it before asking. It's written for people who already know who the author is. Hence the question.

Staying out of the public eye for his entire tenure. I remain envious.

Some mozilla software developer I guess.

They still have not fixed their build system. Meson/ninja or cmake would be alternatives. Nothing to have them abandon mozconfig ... this is legacy code. The rest of the world moved on. Mozilla lives in the past.

FWIW the Firefox build instructions [1] look a lot saner to me than the Chromium build instructions [2].

And one would hope they stay there, because all the newer stuff is far more user-hostile.

Could not agree more. I am honestly confused by the need for more than what FF/Librewolf offers and have been actively doing frontend for a long time. Plus no hassle with uBlock. And their Focus mobile browser is nice. I have the same complaints about their leadership as most but at least I feel I have some autonomy with their browser.
