Simply great :-)

Funciona perfeitamente como informado

Make sure to enable this for JavaScript (https://github.com/gildas-lormeau/SingleFile/blob/master/faq.md#why-dont-interactive-elements-like-folding-titles-dynamic-maps-or-carousels-work-properly-in-saved-pages).
Works great! However, I really feel like saving scripts, audio elements, etc. should be enabled by default.

very very simple
I liked Mozilla Archive format, but it is not compatible with new version Firefoks. Therefore I look for the capabilitise for save page to read it off line. I Explorer give such functionality. Single file is good add-on

Love this add-on. I have been using Singlefile for perhaps a couple of weeks with firefox mobile and so far it has worked flawlessly. Thank you, to the developer!

very good extension. it is different from mhtml, it is html, it save image to base64, not a image.

This works great and better than a PDF export because it preserves the code underneath and the links. It has a host of well thought out options. You can easily export the pages this add-on generates into PDF if needed. An exceptional way to archive pages. Oh yea.. it's also on GIT!
