Sorry, but what is that supposed to mean? Have you looked at Chromium's (or any other modern browsers') memory usage? Firefox is timid compared to it, and always has been so. Maybe it's not due to the browser engineers' low skill level, but due to the enormous complexity of modern web? It's a separate operating system on top of your operating system.
