Pages navigation menus or text is all over the place and overlap other elements no different than the normal print dialog

Doesn't work as expected - prints only the visible portion of the page.

Doesn't work when the webpage was generated by a logged into website that posted information from a database.

Garbage. Produces the same thing as the print dialog.

Ne fonctionne pas sous Firefox 58.0.1 sous android nougat 7.1.1

it can't save web text tidy

Does not work in FF57 on Mac.

So far, does not appear to work at all with Firefox 57+ and Mac OS High Sierra.

on linux the addon only save a blank file (o bit)

The page I was looking at had a section with a scrolling section of text. This did not capture all of the text in that scrolling window, so didn't work for me.
