Comment 2

[ISHIKAWA, Chiaki]

This error also show sup in C-C TB |make mozmill| test suite runs.

     29 [17983] WARNING: No inner window available!: file /NREF-COMM-CENTRAL/comm-central/mozilla/dom/base/nsGlobalWindow.cpp, line 9694

Also, actually, I see more of them if I run C-C TB under valgrind to check memory-related runtime errors. Valgrind slows down the execution very much.

I suspect there are code that ASSUMEs that the inner window appears much quickly while it may take time for an inner window to appear on the screen: maybe proper wait is necessary rather than trying to poke/probe inner window and failing before such inner window is available ?

I don't see this warning in the top 100 on Linux64.
