Details

When images are disabled <link> favicons are not loaded but /favicon.ico ones are.

Steps to reproduce:
1. Disable images: Goto Tools->Options->Web Features and uncheck "Load Images".
2. Visit the URL ( http://bugzilla.mozilla.org/ ).
3. Notice how the favicon is *not* shown.
4. Visit somewhere with a /favicon.ico (e.g. http://www.google.com/ ).
5. Notice how the favicon *is* shown.

Disabling the content policy check in onLinkAdded in tabbrowser.xml bypasses the
problem. I'm not sure what's more appropriate but it would be good if either all
favicons loaded or none did (I'd prefer the former myself).
Just to add something, not all <link> favicons fail, just those using certain
image types. For example MozillaZine Forums ( http://forums.mozillazine.org/ )
declares its icon as image/x-icon (and sends it as text/plain) and that icon
loads with images disabled.
Though it seems that http://forums.mozillazine.org/favicon.ico exists anyway so
perhaps it is being loaded it via that route.
Hmmm.. I'm not sure how strictly we want to interpret don't load images.  I'm
thinking if the user has image loading disabled, they're trying to minimize the
amount of data tranferred (and amount of net connections that get used).. not
loading favicons would help towards this goal, no?  On the other hand, they're
tiny..

Using Mozilla Suite 1.8 alpha3, no favicon at all are shown when "do not load
any images" is choosen. 1.8a2 was good (icons were shown). 1.8a3 displays
nothing (grey zone) in the personnal toolbar and in the bookmarks.
