Is Diigo Web Collector - Capture and Annotate safe?
Diigo Web Collector lets webpages trigger cross-origin image fetches and uploads the image data to Diigo.
The extension accepts page messages that provide an image URL, asks its background script to fetch that URL with extension permissions, and converts the response to image data. It then uploads the image content, along with source page metadata such as URL and title, to Diigo's toolbar service.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 24 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.
