For me, PrintFriendly & PDF is a must-have Firefox extension that I use every day to "clean up" and file web articles. It has allowed me to go almost totally paperless with my reading and reference materials.

This extention automatically strips out extraneous text and graphics and gives me the ability to quickly remove other items that I don't want included.

Because many authors now put multiple articles on the same webpage, I wish that PrintFriendly & PDF provided a "bulk delete" function that would let me remove large amounts of unwanted text from a webpage quickly.

Otherwise, it's great and an extension that I couldn't live without!

Doesn't work perfectly on each single page, but considering the lack of alternatives, I very much value the effort put into this add-on. When it works (most of the times), the page is really clean and tidy. The options to modify text and image size are definitely a great plus.
I'd recommend the following to improve on usability: 1) loading the preview header as docked, so it stays there when scrolling down; 2) not duplicating the button to save PDF, let me just click once; 3) loading the preview overlay as a lightbox, so I don't have to click into the small icon to dismiss it; 4) When saving the PDF, add the name of the website in the end rather than at the beginning (or give me the option to choose); 5) give me the option whehter I wan to reduce the image size or not.
Doesn't seem seem to work with reddit pages (where everything else fails, as well), and few others (such as www.scmp.com).
Thanks for the hard work.

excelente resultado, crea una vista de pagina muy limpia

excellent result, create a very clean page view

Really enjoy this extension. This extension not only can help to make some web pages readable, it also allow you to remove information from pages that aren't relevant to printing. Also allows you to resize images, and remove others, so you're not wasting printer toner on things you don't need. While there are pages that prevent it's use, those pages also disallow Firefox printing. Unfortunately for some pages all you can do is use the "other" browser to print. Not the fault of the extension or Firefox, it's how some folks build webpages.

Print friendly and PDF allows me to preview the document and remove unwanted sections with an easy user interface.

very useful extention! you can also manually delete unwanted page elements from pdf.

Simple and effective. The best way I've seen so far for saving webpages in pdf format.

After UnMHT was discontinued, i've been looking for a plugin to save articles just as easily (less than 30 seconds per page I save and no editing of the saved page) and make it just as easy to index and read. I have found it. This is a life saver for me.

This app has made my life so much easier in regards to researching!
You have made a GREAT CONTRIBUTION to mankind!
Thank you so much, for what you have done!

Very useful. I just wonder how to have A4 format by default

Absolutely fantastic! It cleans up the web pages beautifully, and lets you save them to PDF for future reference. Thank you, thank you, thank you! Only gripe is... why do you use my preferred page content language for the UI, when my Firefox is in a different language? My UI is English, my page content is Norwegian. Don't mess with it :-)

I love this extention. Creates great looking PDF's and allows me to remove any unnecessary cruft.

¡Genial! Buscaba algo para imprimir páginas webs en PDF (siempre usaba CutePDF writer pero el algunas webs me salía mal el documento y no lo podía editar bien ni importar para editarlo) y esta extensión lo hace quitando la publicidad del documento.

Very useful!!

EDIT (after developers comments):
Thanks to the developers for their quick action. Indeed, you should download the extension from their website to have the same experience as in Chrome. The version on FF store sucks due to FF store limitations.
Not only you can print and/or save a page as PDF, but also you can clean the page from unwanted sections like ads or side bars. Great extension! Thank you.
