Created attachment 346155 [details] testcase This assertion appears on any site that uses AdSense. Reduced from http://pagead2.googlesyndication.com/pagead/show_ads.js. ###!!! ASSERTION: already initialized: '!mInited && mPluginMimeTypeCount==0', file /Users/jruderman/central/dom/src/base/nsMimeTypeArray.cpp, line 225 The patch in bug 461560 changed this assertion, so maybe this is a regression from that bug?
Pfff, I messed this one up pretty badly.
