"cannot save prefs from content process"

It doesn't look like much has recently changed in libpref related to this assertion.

Gregor, is there something wrong with test_settings_events.html?

I'm quite doubtful that the test is at fault. It's hard to say what's triggering this, unfortunately, since the list at http://mxr.mozilla.org/mozilla-central/ident?i=SavePrefFile isn't small and the clearly-b2g-related ones don't look like culprits to me. The best solution might be to change the triggering assert to a warning.

Hm we might check the pref when we generate the mozSettings binging on the navigator object. I believe we access a pref there. Reuben knows where this code lives.

Comment 4

[Reuben Morais [:reuben]]

Nah, generated bindings only do a Preferences::GetBool("dom.mozSettings.enabled") check to see if the interfaces should be exposed, and this test doesn't even use navigator.mozSettings.

[Gregor Wagner [:gwagner]]

Right thats only a get. The only other option I could come up with is an observer that listens to this event. But also not very likely.

FxOS/Gonk has been removed from the codebase. Mass-invalidating FxOS related Device Interface bugs to clean up the component. 

If I incorrectly invalidated something, please let me know.
