894451 - Firefox should ignore blank longdescs rather than replace them with the URL of the page

Status: REOPENED

(Firefox :: Disability Access, defect)

Description

[Jennifer Morrow [:Boriss] (UX)]

Bug 877453 exposed longdesc in image context menus, but it is not yet exposed in images which are also links which contain longdesc.

Steps to reproduce:

1. Go to https://blog.mozilla.org/faaborg/2007/06/01/the-user-interface-of-firefox-3-features/
2. Right-click on any of the images in the blog post

Result: See context menu for a standard linked image

Expected result: Also see link to Description in image, since the images all have a long description

Unless I'm missing something, the longdesc attributes on those images are blank, which isn't a valid longdesc value [1], so I wouldn't expect them to show the context menu item. If you try for example [2], it works as expected.

Feel free to reopen if I'm mistaken.

At first I was confused about why the link images in https://blog.mozilla.org/faaborg/2007/06/01/the-user-interface-of-firefox-3-features/ show longdesc in the Page Info window but not the context menu, while the image links in your [2] link above show longdesc in both the Page Info window and the context menu.  Then I looked at the source on Faaborg's blog:

> longdesc="" />

...he appears to have left the longdesc attribute blank but present, which produces in Page Info a URL for longdesc which is just the URL of the page that the image is in.

This is pretty minor, but we should just ignore longdescs that are empty rather than show a URL for them in Page Info.  I guess I'll change the title of this bug and reopen it

I think this is a bug in page info, not a11y APIs, so moving.
