Package: iceweasel Version: 42.0-1 Followup-For: Bug #795436 I also had the same problem. inContent preferences use, for several dialogs, fake windows that cannot be detached, that do not respect the general GTK style, that use inferior widgets and often do not resize properly (content just overflows or breaks when shrinked below a certain size).
It is a regression in every sense. And now, with ff/iceweasel 42, the fallback is gone. Oh, and meanwhile ff 42 adds a new "settings" icon in the new empty tab page, with a *new* animation that cannot be disabled. Way to go Mozilla.
