Default application for PDFs

Firefox Other

Recently, when I try to open an PDF, it opens in a new Firefox window, although I have Adobe Acrobat DC installed and working. I have tried changing the Firefox settings but this still happens. How do I stop Firefox being the default for opening PDFs, please? I suspect Firefox seems to think PDFs are HTML documents.

Ah, fixed it by changing the Windows defaults; no idea how they got changed in the first place, though.
