Disable Google docs in Dolphin Mini?

The answer to how to download PDFs leads to a link describing that Dolphin mini uses google docs for opening pdf and other documents . From a programmers perspective this is a nice solution - the content is just passed to a web-service that displays the content on the browser. But what if you do not like Google to read your pdfs at all? What if you want to download a pdf, but the links to do so is generated so you can not press longer on it to start a download instead? So as a follow up this question arises: How can I completely disable that google-docs-feature in Dolphin Mini?
