Is ClipSave Facebook Video Downloader safe?

Clean risk

ClipSave Facebook Video Downloader opens clipsave.net with encoded Facebook video links when users click Download.

On Facebook pages, the extension adds a Download button to videos and requests Facebook's video_data_async endpoint with the user's session to find SD/HD MP4 URLs. When the user clicks Download, it opens a clipsave.net download page with a compressed, base64-encoded payload containing the video URLs, thumbnail, title, and timestamp.
