Is Extension source viewer safe?

Clean risk

This extension lets you download and view the source files of browser extensions from their store pages.

It adds a toolbar button and context menu options when it detects Firefox add-ons, Chrome extensions, and related extension links for Opera, Edge, and Thunderbird. The source viewer opens in a new tab with file browsing, search, syntax highlighting, code formatting, image preview, hash display, embedded zip viewing, and download options.

Shared hosts - 1 hostname

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.
