Bookmarking PDF in Google Chrome
===

Lately I've been reading a lot of PDF books using Google Chrome. To go to a particular page, you can simply append #page=23 to the url (as in file:///C:/my_book.pdf#page=23). This is a nice and easy way to bookmark your current page number to continue reading the book later.

**My question:**

What's a way to find out what page you're currently in within the book?

OR

What's a Chrome plugin that bookmarks PDF files within your file system? 

I've tried a few extensions, but they don't work unless the book is in a server (as in http:// localhost/my_book.pdf), which is not desired in my case.

Thanks!
