Some time ago my Chrome started to open PDFs in Google Docs viewer. I don't really know if I did something to force this behaviour, but I would like to view it as I was before (using Foxit Reader plugin).
Every link to a pdf file is replaced by Chrome: https://docs.google.com/viewer?url=http://url.of.the.pdf
Have googled a bit but I can't find how to disable this 'feature'.
