Description

I'm on Windows 10, last fx-team update: 49.0a1 (2016-05-17)

STR:
- open a tab on https://www.mozilla.org/en-US/
- open the webconsole once so the scripts load
- close the webconsole
- now open the Browser Toolbox
- open console-output.js in the debugger tab of the Browser Toolbox
- set a breakpoint in the Messages.BaseMessage constructor (this also happen with other panels and other scripts, as long as there's a breakpoint)
- now come back to the browser tab and open the console

In my case the browser becomes unresponsive for ~30 seconds, or even (in some cases) shows the "slow script" dialog, until it finally loads the UI of the console and the breakpoint is hit.

This didn't use to happen, so flagging as a regression, although I don't know when this started to happen.
I've witnessed this over the past 2 or 3 days.
