Sure this add-on has it flows like when it's installed the favicon on tabs will disappear.
But out of all the add-ons I tried today this was the only one that was able too restore and update some of my bookmarks favicons in my huge collection. After I was finish fixing my favicons in my bookmarks and tab bar, I removed it. All your edits will remain even after it's been removed.
You install it do the edits and remove it again and all Firefox functions is back too normal again.
imo it's still a very usefull add-on and if the bugs gets fixed I'll gladly give it a 5.
