Samsung Chromebooks

I've had my Samsung Chromebook Plus for about six months. I've been pretty satisfied so far. (Still don't like Office) But, I've noticed of late that when using Chrome Browser, I cannot open any PDF links.

I've visited many pages with PDF links. I have Xodo for opening PDFs from my files. (which is no problem) I've tried other extensions. I go to Settings/Advanced/Privacy/Content settings/PDF and the only option is "Download PDF files instead of automatically opening them in Chrome"...
