Thank you, it works!

I prefer to open PDFs by my default viewer (Foxit), however I can't find the option to turn the feature off that opens pdfs in browser tabs. This wouldn't be so bad, however opera UI completely hangs one out of 2-3 times after opening a pdf (I have to kill it from taskman). I assume Adobe reader loads the pdf, however it still does after I turned off the option in Adobe Reader.
How can I change the way pdf-s are handled by Opera?

Thank you!
