No mention of the tools/methods used to do the profiling, I think that would be the most interesting part.

Also a bit surprising that a checkpoint with the browser running wouldn't just work. Is this some quirk of firecracker?

Checkpoint with Chromium running is possible and will be our next step.

Main blockers right now is fingerprint injection and profile injection, solved already.

It's always a balance of engineering effort & gains. Post-Chromium snapshot let's us save 200ms, which is not that important for 99% of use-cases, but that will come soon since it brings some other benefits (like CPU footprint)

Profiling and tools used are already included with Chromium, they provide nice debugging tools

Do you do this at the chromium/V8 level or CDP?

I've been having mixed success with CDP and was thinking of going to the level below, but it feels like just getting Chromium itself to baseline chrome detection profile is significant work

Deepest level possible, harder but required for some workflows
