Save ink! replace all images with blanks before printing.

This extension is designed for quick use. It features a simple button with no customization options. The extension replaces all images on a web page with blank placeholders, rather than removing them entirely. This prevents layout issues while saving ink when printing.

Limitations:

All extensions can work on web sites ONLY - The extension will NOT work on pdf files.
All extensions can't work on the Firefox add-ons site.
The extension activates a few moments after the page fully loads.
You cannot select which images to remove.

How to set up:

Press the puzzle icon near the address bar and then press the gear next to the extension - choose "Pin to Toolbar".
