I remember needing Adobe for the pdf files I occasionally need to view but that appears to be the only thing I need it for. But this brings me back to a basic "do I need" question for downloading/installing Adobe Flash Player just for PDF files?
If you use Chrome then no, you don't need Flash Player. It is built-in (or rather bundled).
Flash Player is unrelated to PDF files (you're thinking of Adobe Acrobat Reader) and is mainly used for video, animation and games on websites (although it's falling out of favour now that HTML5 is well-established).
Chrome also has a built-in PDF viewer (as does Microsoft Edge) so you don't need Acrobat Reader either.
