Thought "behind the scenes" in the title, three authors with good credentials, and featured article category, would mean the article presents some interesting technical details about the bugs, from which a software engineer could learn to plan better programs. But the article is just a verbose, non-technical ad for Claude, same as "The zero-days are numbered" by Firefox CTO in the Mozilla blog.
I'm still sure that direct monetary investments in work on software commons, from public budgets, without AI sellers in the middle, would result in similar or better fixes while producing public knowledge and new generations of specialists. Anthropic isn't doing a public good by donating early access to an LLM API to Firefox developers, it's doing extortion: we'll sell this model to anyone who pays, including your enemies, so give us good PR if you don't want them to get it first.
