Is GRUU VIEWER safe?

Clean risk

GRUU VIEWER sends a selected image or video URL to viewer.gruu.jp when you use its context-menu viewer.

When you choose the GRUU VIEWER context-menu action on an image or video, the extension posts that media URL to viewer.gruu.jp for rendering. It opens a local form page that submits the selected URL as img_url to the service endpoint.
