The answer appears to be no - there is no built in function in Firefox to HTML-encode a string from an XPCOM component.
In theory you could create an XML document, use that to create an HTML div, set its text content to your unencoded string and read off its innerHTML. Note that this only encodes lt, gt and amp characters, not quot.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
