I can look into this.

So, there are two issues here.

The main issue with about: pages is that we don't store about: URLs in history, so we're not finding a favicon for them when we call getFaviconForUrl in readLastTabs. The favicon *does* show up for about:firefox because it's a bookmark, so if you bookmark about:feedback, you will see the favicon show up ;) I'm not sure if it's worth fixing this issue, since it's rooted in how we handle history entries for about: pages.

The second issue here is that when we don't find a favicon, we never end up calling updateImage, so we get that awkward white square. This is something that should definitely be fixed.

Here's a patch to fix the second issue I mentioned in my last comment.

This was a regression from bug 839855 (I tested in beta, and we show the default favicon for about:feedback in tabs from last time).
