Not working
Hi, The extension doesn't appear to be working any more? Studocu is asking to login/pay for premium, and not allowing downloads? (And sometimes, the page breaks entirely)
Tried on multiple devices, latest version, etc.
same issue, it loads few pages of any document but missing a lot of parts.
@darren89d, @conallfowler Replace the code in doc-viewer.js with this. The issue is, that the content is loaded as you scroll through. This way, it only fetches the first 10 pages. The added functionality scrolls through all the way to the bottom and then opens the print view; this way, all the content can be fetched. Additionally, the print view showed the premium overlay. It would disappear when you hit print, but this way, it is also hidden in the preview.

if (width > height) print_opt = "{@page {size: A5 landscape;} body {zoom: 90%;}";
else print_opt = "{@page {size: A5 portrait;}";

Hi, the banner problem is solved, but not for the blurred pages on Studocu. Usually the blurred pages are from the third and multiples. I downloaded the lastest version of StuHack.
Hi, I found a bug, the pages that were previously blurry are no longer blurry, but instead of the page that should be there there is the previous page, for example if page 3 is blurry, by clicking on download page 3 is not blurry because in its place is page 2, which is thus repeated twice, thus for all the pages that should be unblurred. Another question, when you update to the latest version I just need to download the latest version which is called stuhack-master and that's it right? Thanks for your time!
