Don't despair! There is a technical explanation for this which is as old as Firefox itself, and a couple workarounds.

The Page Info dialog only shows media used in the "main" page listed in the address bar. In this case, the eBay seller is embedding a page from another site using a frame. The Page Info dialog doesn't list the media displayed in frames.

In order to access the Page Info tab for the framed page, it's usually easiest to pop that frame out into a new tab. To do that, right-click a blank area near the first of the additional images, click This Frame, then Open Frame in New Tab. (See attached screen shot.)

Sometimes, a framed page won't display outside of the original page. In that case, the This Frame menu also has a View Frame Info command.

Fred, I'll try those things; but as I said this is a brand new install and new computer. On my previous computer (Dell Windows 7 Home Pro or Premium, I forget) I never had this issue (with an older Firefox).

jscher, sort of the same answer. You're right about the frames; but this never posed a problem with my previous set up. They indeed are images 'served' from and outside source. But I didn't have this problem before, except that on some occasions a couple of images might not save properly. They either could be saved individually, ignored, or not be able to be saved.

I'm sure I could save the images one at a time; but that's an extreme hassle. Before, I could select all the images and save to one folder. Very convenient.

Edit: Thanks Jscher, that actually does give me the correct image choice. In this case, they all have the same name.jpg, which means I'd still have to do it individually (which has been the case in the past); but why is this all of a sudden a thing? I've never not at least been able to access the images in the first Media menu.

I seldom need to save images in bulk, so maybe you have noticed a change that I haven't noticed.

Regarding the file names, the site is using very odd names where the part that varies from one to the next is the folder name and not the image file name:

Either way, it's gibberish. Thank you, eBay.
