Question

Is there a plugin for Firefox which will save an image in a tab once it's fully loaded and close the tab all automatically without user interaction?

The key thing I want to stress is that the plugin should automatically save the image in each tab once the tab is fully loaded if the tab only contains one image to a predefined folder. I have plugins that can save all images in tabs when I click a button, but I need one that will auto-save all tabs with only one image then close the tab WITHOUT user interaction.

I have done a lot of searching but haven't come up with anything yet. This seems like a really useful plugin and since there are similar ones out there (not fully automatic) I figured someone must have written one already so I thought I would ask my fellow super users.

Sounds like a job for GreaseMonkey.

What does Greasemonkey do?

Greasemonkey lets you add JavaScript code (called "user scripts") to any web page, which will run when its HTML code has loaded. Compared to writing extensions, user scripts often offer a light-weight alternative, requiring no browser restart on user script installation nor removal, and work with the common DOM API familiar to any web developer (with somewhat elevated privileges for doing cross domain XMLHttpRequest requests and storing small portions of private data). User scripts work more or less like bookmarklets automatically invoked for any URLs matching one or more glob patterns.
