Download Image from Context Menu από Erisa

Extension that adds a context (Right click) menu item to images which allows you to directly download them without a prompt.
This simple idea for an extension was born from saving multiple images at once, and rapidly pressing enter after each save to go through the "Save as" prompt.

Notice:
On Firefox, the tracking protection feature may sometimes interfere with this extension when set to the "Strict" option.

This interference will prevent the extension from automatically generating file extensions for images that do not have them in their filename. If this happens, you may have some image downloads which do not have valid file types. This does not affect the contents of the file, and they can be opened normally if a valid extension is manually provided.

The only known workaround at this time is to set tracking protection to the "Standard" state.
