Comment 181 for bug 747197

I feel inclined to develop a Firefox Add-On for this. To me, this seems overly simple.
1. Just take the download tree (e.g. as seen in Firebug ect.) and redownload it all.
2. Save all files to a folder as is (which is, if I remember correct, the current behavior).
3. Parse all css/js files and replace URI's to local path.
4. Have heaps of fun with script loaders (AMD et al.) making NO. 3 difficult.

There you have it. The page, saved in it's entirety.
