I may have mis read your note but have you tried FicLab?
Yup. Tried, but I don't have the admin right to install any extension myself (just realized I used the wrong term), so... now trying to look for direct download whenever possible.
If the story is on AO3, you have the ability to direct download a copy using the site's program, without having to install anything on your computer. You might also be able to do that on Stars Library. Click on the printer icon, then save to pdf.You can't do it from ffn, though. You have to have a third party program. Although, I have heard you can cut and paste if you're using the mobile site for ffn. I don't know if that's still true.
don't know which thread is the discussion thread.... I'm knew to the website and don't have it bookmarked yet 0.o Are you sure you have the right website? It is just one page with a box to put in the URL, a drop down menu to pick format, and a dowload button. Like I said, it only does FF.net right now because it is fairly new (there is a list of updates at the bottom of the page)
