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'.

To disable Chrome from automatically using the Google Reader, go to "chrome://plugins/". Then locate and disable the plugin called "Chrome PDF Viewer". When this was installed, it should have automatically disabled your previous reader, (mine happend to be Adobe Acrobat, but this should work anyway). Then find your Foxit Reader Plugin entry, and re-enable that. Should work as soon as you load a PDF. You might want to restart Chrome to make sure, but for me it worked simply with a new tab.
