Great addon, great to just kick out unwanted elements, still one thing is missing: One should get the chance to adjust the background color. I do print science website content frequently and there are always authors who publish their diagrams as .gif or .png with transparancy and white lines on dark background.
My workaround for the moment is to generate the print page, rightclick on the background and adjust the CSS backgroundcolor-tag to something appropriate like #444 with the developer tools, then print the document NOT with the addon but with the standard browser print function.

Hope one of the developers reads this, thanks!

best I've found for this task

would be nice if it was more careful about including source / author / date etc - I often have to edit the pdf after to include this info

Almost perfect.
Suggest that the page it creates is a new tab, which seems pretty standard for most applications, rather than using the existing tab.

Brilliant little app, should come as standard on all computers.

Если на странице есть вставки BMP, аддон их выкидывает сходу. Знаю, что такое бывает редко, но страницы не я создавал, но сохранить не могу(( А жаль, адон оч клёвый и продуман хорошо(((

Works quickly, and without any fuss.

I tried many extensions and this one offer the best result. Keeps the text, so you can search a word or copy/paste from the PDF and lets you clean the page easily before. So good!

Works on Firefox 56 and ready for Firefox 57.

EDIT: good to print the text and also some pictures of a web page, not to keep a perfect copy of a web page in PDF.

I wrote before:
Quite a usable tool. But without options to set, it removes also images that i would like to keep. My suggestion is, to add a feature that allows to configure the options or settings for each image: to allow or hide.

You answered:
It should keep all the images by default. Can you provide an example site where you are experiencing the problem?
