I largely agree, but however far Mozilla is from the peaks it could theoretically be on, I still wouldn't criticize it like this without qualifying my complaint by adding the fact that it still has much lower to to sink before it's as bad as Chrome.

I don't use Firefox anymore and I don't love Mozilla, but I appreciate the efforts they do make in favor of privacy and interoperability and especially the fact that still make the best fairly drop-in alternative to the engine with 80% domination of the browser market. I still would recommend Firefox to any nontechnical person who uses Chrome or Edge now (it's at least as fast, uses maybe 40% less RAM, and just happens to be less evil). (And I personally still use a browser that benefits from their work, Palemoon, which is also flawed (corrupted to a much smaller degree than FF by a much less evil search engine than Google — DuckDuckGo — but I'd use any browser —even the old Edge, if someone maintained a version for my OS— that's not based on Chromium, if it slowed down the growth of Google's evil empire/monopoly)).
