Created attachment 548452 [details] testcase 1. Apply the patch in bug 90268. 2. Make a 32-bit debug build (so Flash will work). 3. Load the testcase. 4. Quit the browser. Result: ###!!! ASSERTION: Remote window should be null.: '!aWindow.window', file dom/plugins/ipc/PluginInstanceChild.cpp, line 2328
This should be fixed in the latest version of the patch on bug 90268. Jesse - can you confirm?
I don't have Flash installed now.
