Firebug breaking Session Manager Addon on Linux machines (preventing Firefox startup notifications)

[Morac]

I've gotten a few emails about Session Manager not working after the Firefox 30.0 update on Linux systems. In all cases, disabling Firebug 2.0 fixes the problem. Looking at logs, I see that none of the usual Firefox startup notifications, such as "final-ui-startup" are firing.

I could not reproduce this problem on my Windows 7 machine, but several Linux users have reported it.

.. so, it isn't forgotten her in the noise.
