A Chrome step toward saving PDFs in Diigo

Having abandoned my search for an easy way to save pdfs to Diigo, it happened accidentally by just using Chrome. Chrome opens pdfs inside a browser tab, where my Diigolet works comfortably. However, there are some problems.

The biggest is that I cannot highlight. So I can save but not annotate. When I try, this happens:

Also, it can’t grab the title of the work, so I have to title it manually.

But it’s a step in the right direction, I think.
