Mozilla lays off 70

Not sure of Mozilla’s financial or organizational structure but it seems to be part of a larger trend of de-emphasizing QA departments at software shops large and small over the past 10 or so years.

In many ways test automation tooling has become much easier to use, develop, and manage.

But I suspect the larger driving force is that it’s (arguably) a cost center for an org. The burden of ensuring software quality can be shifted to devs and PMs, though usually with mixed results.

For Mozilla, axing quality and security first is a bad look when those are crucial aspects of a privacy-first company value.

Mozilla uses AFL, which is a genetic algorithm that tests code paths. They are also transitioning to Rust, which will give them a much bigger safety guarantee over most of their code and a much smaller audit surface for the rest.

American Fuzzy Lop? It's a fuzzer. I've never heard of a fuzzer described as a genetic algorithm that tests code paths, but that is technically correct.

A fuzzer is not going to replace unit tests or good SDLC, which often involves QA.
