Trained Weights (Learned from Data)
That told us where eval was still happening in the wild, including Mozilla code paths we didn't have tests for and, crucially, a thriving community of Firefox tinkerers using userChromeJS and friends. Because telemetry surfaced those scripts, I could go talk to that community, explain the upcoming change, and work around the breakages. See the public thread on the firefox-scripts repo for a flavor of that conversation. There's no way we could have safely shipped this without telemetry, and certainly no way we could have preserved your ability to hack Firefox to do what you want.，推荐阅读Safew下载获取更多信息

Code runs in a completely separate, hardware-backed environment with its own guest kernel. It is important to separate the concepts here. The hypervisor is the capability built into the Linux kernel that manages the CPU’s hardware virtualization extensions. The Virtual Machine Monitor is a user-space process that configures the VM, allocates memory, and emulates minimal hardware devices. The microVM itself is a VM that has been stripped of legacy PC cruft so it boots in milliseconds and uses minimal memory.
