Brief title:
Jump to specific page in pdf document via URL (browser extensions)

Description of desired feature:
When doing research for university, I often open many tabs at once. Sometimes books in pdf document form from my local file system. When closing google chrome and reopening on the other day, the document opens up at the first page. It would be nice if a) the document keeps its position when closing the browser and reopening, or b) via an #[pagenumber] at the end of the URI in the browser I can navigate to specific pages, especially on browser reopening - like on websites when jumping to another anchor item via this function.

Why the feature is needed:
It would save time for me as a user when I dont have to search for the last page I have been reading in the book/document.
