So, this restartless and lightweight add-on (4KB code, 8KB package) should make things nicer for those of you who like to use them.
This add-on provides a preferences window where you can define a URL, Image, and Toolbar ID - being the two later optional. If no image is specified the website's favicon will be used instead.

Q: Reinstalled the add-on and the buttons are missing, even though they show up on the options.
