## Review summary

Reviews are mixed: multiple users praise the add‑on for previewing web‑hosted Office documents and say it’s essential when it works, but many others report it is unreliable — forcing downloads or showing blank pages — and has inconsistent support across file types. Common complaints also include inability to open local files and poor UI/toolbar integration or documentation.

### Pros

- Previews web-hosted office documents (DOC/XLS/PPT/XLSX) for many users when it works
- Several users report it works reliably for them and is a useful/essential add‑on for viewing documents online
- Integrates into browsing so you can open documents from links/pages without leaving the browser (for supported links)

### Cons

- Often fails to open files for some users and instead forces download or shows a blank/grey page
- Inconsistent file‑type support — users report problems with PDFs, PPT/ODT, RTF and some XLSX/CSV link formats
- Cannot preview local/desktop files — only web‑hosted documents are supported
- Usability issues: no obvious toolbar icon/options or clear instructions; link placement/formats can prevent the viewer from appearing
