It looks like Mozilla's average SDE salary is about $120k, so yes.
The national median software developer salary is something like $110k. The middle 50% range is like $85-150k, so if you're making above 150k TC you're already in the top 1/4 of developers, who are already very high up in general.
I say this because people on HN love to pretend that "industry-standard" means $250k+ for new grads and $400k for experienced ICs when that's just not true. FAANG-level salaries (which can absolutely be 300, 400, 500k TC) are the 1% of the 1%.
