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!
