Firefox & Exchange 2010 Critical Error

After updating Firefox today I encountered the following error when trying to work with the Exchange Control Panel in Exchange 2010 RTM:


Going by the message, “Permission denied for .. to get property Windows.frameElement from”, it looks like a cross-site frame protection issue. I don’t know if the update is responsible for this (Firefox 3.6.8) or this is also the behaviour of earlier Firefox versions. I checked it against IE and that has no issue.

So far for multi-browser support.

  1. I’m having the same thing happen to me in Firefox (I’m using 9.0.1) where I get the following error message:

    Error: Permission denied for to get property Window.frameElement

    Kind of annoyed because it keeps happening even when I close the window. It comes back again! Anything fixed on your end?
