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.
