Admit that this could be useful. But after removing it my bookmarks without icons are staying with hased colors, though default icon is shown on tabs. Try it with CARE and backup your profiles before. Also, Settings without any text? It's not so intuitive as you may think.

This review is for a previous version of the add-on (0.4.17). 

This is a good point. I shall give it some more thought but, as there is no interface to disassociate an icon from a page, I can't see an easy solution at the moment. The same thing would happen, without this extension, if a site stopped providing an icon.

edit: This has been fixed in the next version. [For anyone needing to clear HCT+ icons kept after an uninstall, the following should work: Install 0.4.18 -> (Restart) -> Uninstall 0.4.18 -> (Restart)]
