Save web pages as self-extracting HTML/ZIP polyglot files
SingleFileZ is a fork of SingleFile (https://chrome.google.com/webstore/detail/singlefile/mpiodijhokgodhhofbcjdecpffjipkle) that allows you to save a webpage as a self-extracting HTML file. This HTML file is also a valid ZIP file containing all the page resources.
To open saved pages from the filesystem in Chrome, SingleFileZ must be already installed and the option "Allow access to file URLs" must be enabled in the details page of the extension (chrome://extensions/?id=offkdfbbigofcgdokjemgjpdockaafjg). Otherwise, Chrome must be started with the switch '--allow-file-access-from-files'.
