Jonas, this needs to work from chrome, right?

Not critical for beta8.

Unless we hear of more people having problem with this, we'll unfortunately have to punt on this

I get same error for both web page (please see 'Test page' attached) and chrome (NS_ERROR_UNEXPECTED exception).

1. Doesn't work for FF 4.* (last tests were done on the following: Mozilla/5.0 (Windows NT 6.1; rv:2.0b11) Gecko/20100101 Firefox/4.0b11)
2. Works for FF 2.* and 3.*

Web page case can be skipped since there is no exception after adding domain to whitelist.

But there is still exception when running from chrome and output nodes have xul namespace:
[Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIXSLTProcessor.transformToDocument]"  nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)"  location: "JS frame :: chrome://.../content/t.js :: <TOP_LEVEL> :: line 8"  data: no]

XUL namespace can be defined stylesheet and it works to match input XUL nodes. Exception is thrown if output nodes need to be with XUL namespace.
