Out of ~470,000 crash reports in one week, ~25,000 showed potential bit-flips — suggesting up to 10-15% of Firefox crashes are caused by faulty hardware, not software bugs. The memory tester (checking up to 1 GiB in 3 seconds) confirmed genuine hardware issues in roughly half of suspected cases. The thread discusses implications for ECC RAM adoption, physical memory address ranges, DRAM shrinkage increasing error rates, and the industry's tendency to ignore hardware memory failures. The author argues this problem is vastly underestimated and affects all consumer devices. ## Full article daily.dev links to this article rather than hosting it.
