Reproduced intermittently with Firefox 34 beta 9 under Win 7 64-bit.

Steps to reproduce:
1. Open WebIDE using a profile where simulators were previously installed
2. Connect to any simulator
3. Add, open and debug different hosted or packaged apps
4. Disconnect

Expected results:
Simulators are correctly closed

Actual results:
Sometimes, the pop-up "Plugin Container for B2G has stopped working" with options Close and Search for an online solution is displayed.
Unless we can narrow this down to a more specific set of steps, I don't know if there's much we can do.

Petruta, any idea?

Ryan, I just tried again using Firefox 36 beta 10 under Win 7 64-bit.
I opened the build with a clean profile, went to WebIDE and installed all the simulators at the same time.
Then, I selected 1.3 simulator and debugged Clock app on it.

Without closing the simulator window, I selected 1.4 simulator. From "Open app" drop down I selected Browser app, and debugged the main page (select some tabs from app console too).

Same as above, without closing 1.4 simulator window, I selected 2.0 simulator - the "Plugin Container for B2G has stopped working" window appeared on the screen.
