The previous bug tracking the problem was #8265, "Sidebar won't open". I fixed the symptom but not the disease, so I opened this bug to track the latter. Marking M7.

I know a fair bit about this, but my ideas are exhausted. John, do you have any ideas? My windows box is broken though, so I can't really debug this either.
Because we have fixed the only known use of XPConnected prefs, I think we should later this to M8 and raise the priority.
I agree with slamm. Alec, while I am grateful for your work on libpref, I am really the owner of it, so why don't I reassign this to myself?
M9, giving to don for re-assigning.
this is an old bug, it is all good now. Sidebar is fine, can be opened, closed, and the states are saved
Moving all libPref component bugs to new Preferences: Backend component. libPref component will be deleted.
