Sorry, same Problems others reported:

Does not save from wiki page or reddit. Only saves half of first visible page in browser, rest is missing and duplicated empty frame on more pages.

Fandom save does not work.

Wordpress 5 content not saved, most stuff missing.

Firefox 68.0

Doesn't work at all

Only save first page, then duplicates this to 5 pages...

It saves just what you can see, it doesn't scroll down to the bottom, it's useless.

Does not work on Mac OS. Tried click after click, but nothing. Using Firefox 64.0 (64 bit). It sounds like it would be a useful extension. Hopefully a future release will work on Mac.

It did not work as expected in a simple webpage I tried to convert.

Same as Print to PDF the 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 a page.

Ne fonctionne pas, une daube !
Doesn't work (not wysiwyg) , rubbish

The same as Print to PDF. On same pages just doesn't work

It didn't even come up with the save/open dialog and from there, the choice of directory to save it to. It just did nothing at all. Click after click, nothing. Didn't update download listing bar, either. Using Firefox 56.0.2 (64 bit).
