Its been a couple of years since Ive used the Mozilla libraries and some of
the functionality now seems iffy
For example print preview requests now generate an invalid pointer error
error[Exception... "Component returned failure code: 0x80004003
(NS_ERROR_INVALID_POINTER) [nsIWebBrowserPrint.printPreview]" nsresult:
"0x80004003 (NS_ERROR_INVALID_POINTER)" location: "JS frame ::
chrome://testbrowser/content/proofer.xul :: previewprint :: line 119" data:
no]
Tried the FAQ for print preview and along with all the other FAQ documents,
they seems to be unavailable on MDN
Has the calling syntax for print preview changed ?
Is this just a general depreciation in support for application development?
