torbirdy seems to set thunderbird to automantically check for updates

I am using the recent torbirdy 0.1.0. with Thunderbird 17.0 on GNU Linux.

It seems torbirdy is changing my preference setting for "Automatically check for updates for...Thunderbird" and it also sets to "automatically download the updates."

Even if I change the setting back to do not check, and shutdown thunderbird, the setting returns to automatic updates when I restart.

The problem only occurs when torbirdy addon is enabled.
