My job requires reviewing documents uploaded to an online portal. Most are PDFs so no big deal, but clients often upload in .docx, which opens MS Word when I click the link. This slows my review process and is just irritating. I was looking for something that would open Word documents the same way it opens PDFs. After googling "why can't browsers open Word documents" and reading response after response that it's not possible, this add-on feels like magic - exactly what I needed!
