Latest Firefox version and half of my bookmarks lost their Icon. Great...
The latest version/update installed yesterday and half of my bookmarks on the toolbar or sidebar have now lost their icon. All I have is a dashed square box instead of the icon the web site provides. Reloading the website doesn't bring the icon back either. Deleting the icon and then going to the website brings up the dashed box even in the URL box. Never had this happen before and it happened right after an update. Here's one for our State Lottery,see if you see the same thing.

I encounter this for javascript bookmarks. Lacking a favicon, FF goes fetch chrome://mozapps/skin/places/defaultFavicon.png in lieu of anything else. And it's really ugly looking.
I managed to fix this by building a phony extension which just does an override. The idea is just to follow https://developer.mozilla.org/en/Building_an_Extension, and provide only the following line in chrome.manifest: override chrome://mozapps/skin/places/defaultFavicon.png chrome://branding/content/icon16.png so that if I install my silly extension (less than 1k -- most of it in install.rdf), I get the ffox icon instead of the ugly dashed square.
This silly extension is here, for what it's worth.

You can also specify the icon like this in chrome.manifest:

3 out of 4 people haven't got a clue how to do what you are saying.
Copy and paste the full DATA code in the location bar and press the Enter key.
Save the file as favicon.xpi.
Install the extension via File > Open File or Firefox > New Tab > Open File
