Editing in PDF sounds like a good idea.

I just tried it in Firefox (latest/postmodern, Linux) and none (not a single one) of the form's fields are editable. It's an even worse experience than Libreoffice.

Pdf.js (which Firefox uses) does support filling out Acrobat Forms (acroforms as well as XFA). Possibly the PDF you have is corrupted?

You can read more about PDF.js support for forms here.[0]

Libreoffice also supports creating Acrobat Forms.[1]
