Is Content-Type Fixer safe?

Clean risk

This extension corrects file Content-Type and Content-Disposition headers for page and download requests.

When enabled, it checks new page and download requests for file extensions that should have specific Content-Type headers and can adjust those headers. It can also correct some Content-Disposition filename issues and optionally force inline or attachment disposition based on its settings. It uses web request access across sites while listening, and stores extension settings.

What this publisher told the store about itself, and the other listings that told it the same thing.

Shared hosts - 2 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
