Sometimes Firefox isn't so performant when there are other I/O-heavy tasks in the system. We could use a tool to simulate a slow drive to see where the bottlenecks are. It would be really useful to know which files are being read or written when a hang occurs. If such a tool doesn't exist, we could simply use a rate-limited network filesystem.

Or run it off a USB flash drive. Seriously, Portable Firefox can be brutal at times.

I don't think this is a tool that we have a high need of at the moment. We can collect profiles from some old reference devices which have very slow disks. Here's a recent example: https://share.firefox.dev/46lRqSL
