What camera are you using? Built-in or USB? What type of camera? Can you consistently reproduce this?

I can't reproduce this on my Windows machine.

A system freeze is a bug in code that runs with kernel mode privileges: the kernel or a driver.
The worst thing that Firefox can do is to allocate all available memory but that's easy to check if you have the windows taskmanager already open.

Attachment: memory

It's strange, with last Nightly its work correctly. No lag, no freeze, but a lot of memory used.

After several tests, the memory usage increase  takes place when I have this message "HARDWARE_UNAVAILABLE", when I have the video no problem.
