One Click Image Save by wollomatic

A lightweight Firefox extension that adds a Save image entry to the image context menu and downloads images instantly without showing the file picker.

Features
- No tracking, no telemetry, no ads
- Right-click an image and select Save image
- Downloads start immediately without a save dialog
- Configurable target folder inside your Firefox downloads directory
- Optional website-specific subfolders
- Optional filename prefixes based on timestamp or website domain
- Optional automatic tab closing after the download starts
- Transparent about saved extension settings
- Fully open source

Due to Firefox extension restrictions, downloads can only be saved within Firefox's configured download directory. Custom subfolders are supported, but arbitrary absolute filesystem paths are not.

This extension relies on Firefox's standard image context menu. Images that are not exposed as regular image elements by a website may not be available for saving.
