I can't think of a way to force Firefox to download PNG and JPG images instead of handling them directly -- just as Firefox likes to handle Text and HTML files directly.

Some methods to save the images would include:

• right-click the image > Save Image As
• if it's a link to an image: right-click the link > Save Link As

Or if the image already opened in its own tab:

• right-click the image > Save Image As
• Ctrl+s ("Save Page As" but if it's the image itself, same as Save Image As)

I want to be able to download with out right clicking.

By doing what? What would you want to do instead of right-clicking?

One built-in method of saving images from a page is to use the Media list in the Page Info dialog. You can open that using either:

• right-click a blank area of the page and choose View Page Info > Media
• (menu bar) Tools menu > Page Info > Media

A list of all the media files Firefox has loaded into the page should appear in the box. When you click a file name, a preview image should appear. If you want that one, click the Save As button. Repeat as needed. You might also be to multi-select files to save all in one step by Ctrl+clicking files in the list.

But that's not super-convenient, is it.

Over the years, a lot of add-ons have been created for working with images. Here's one you might find handy: Double-click Image Downloader -- I haven't tried it myself.

There is also the browser.altClickSave pref that when set to true can be used to hold Alt and left-click a link to save this link.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
