Firefox and WinGetText and window info tool

[badcrc]

I've spent quite a bit of time trying to figure out why the window info tool and many window functions don't return anything from Firefox and I thought I'd just ask here so I don't waste anymore time.  When using the window info tool only basic information is returned, such as handle and class, but no text from the current tab/window or any other useful information like control IDs.  When trying to use WinGetText it doesn't seem to error but it doesn't return anything either.  I've tried using the window title, tab title, substring title matches with AutoItSetOption("WinTitleMatchMode", 2) set, exact title matches, and I've tried using the window's handle, which I can get using WinGetHandle, and it's correct, but that still doesn't return anything with WinGetText.  Is this broke with Firefox or should it work?  Is my only option mozrepl?
