Details

STR:
1. go to a simple page (like about:blank or http://everlong.org/).
2. open your CPU use monitor (eg: top on Linux). Observe the CPU usage is very low.
3. open the dev tools using ctrl-shift-k. Observe the CPU usage is still low.
4. switch to the Debugger tab. Observe the CPU usage is big (steadily ~35-45% on my computer).
5. observe that the CPU usage does not change even when you do nothing at all in Firefox.
6. close the dev tools, observe that the CPU usage drops back to a normal value.
For some reason, the only seems to happen on Linux, but we're not sure why.

Hopefully we can figure it out!
