Suggestion for site-wide icons Rated 4 out of 5 stars
Bookmark Favicon Changer has the same limitation as Favicon Picker that it only applies to bookmarked pages.
How hard would it be to collaborate with IdentFavIcon to allow icons to be set for whole domains? Your addon allows for setting a page icon, and IdentFavIcon allows for hash-based autogenerated site icons, so it should therefore be easy to provide custom-selected site icons for sites and servers that lack icons, instead of the cheesy autogenerated ones. I already spend the time drawing nice icons for my bookmarks and it would be awesome if they could take effect for a whole site.
Not a good idea.
Most need different icon for site such as different icon for different yahoo group. Making only one icon for whole site is not a good idea.

Glad to have a favicon changer that officially supports Firefox 4! Mozilla need to hurry up and review it so that it shows up in the add-on search, as it's extremely hard to come across.
Seems to work fine though in Firefox 3.6.16 (I would test in 4, but I had to rip 4 off my work PC after discovering that it's impossible to make middle click open links in new tabs in a popup window (the tabs are forced out to the most recent regular window now, instead of a tab bar appearing in popup window as it did in 2 and 3), which I rely on extensively in our intranet system).
The only thing that makes me nervous is having Change and Remove adjacent to each other, without a "..." after Remove, and I've confirmed that there's no prompt. However, this is just my irrationality as the icon comes back if you re-open the site, and you can restore the icon if you accidentally wipe a custom one, so long as you still have the source file to hand that is!
