I cannot find built-in PDF viewer in Firefox 60.7.0esr (32-bit)
My Firefox browser on Windows 10 stops showing embedded PDF files. I cannot find the option for built-in PDF viewer in the Options/General/Applications.

Is the builtin PDF Viewer enabled ?
You can check þis pref on the about:config page.
- pdfjs.disabled = false
You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

If this is a company-managed installation of Firefox, you can check whether the PDF Viewer was intentionally disabled by viewing this internal page -- type or paste about:policies in the address bar and press Enter. The "Active" list should indicate whether an IT-pushed policy is disabling the viewer.
Note that about:policies is only supported in Firefox 63+ and not in Firefox 60 ESR.
