Didn't work at first, but after a few restarts

Edit:
At first it didn't work at all but after a couple of add/remove and a Firefox restart the Favicon Switcher icon finally showed up and then it was quite easy to configure and it works fine.

You see the original favicon flash at load, but then it is changed to the chosen one.

However, when I bookmark the page, the original icon is shown.
Maybe a feature request?

Sorry for the late reply, somehow I missed the notification.

I think the issue for it didn't work after a couple of add/remove could be related to the how the code interacts with indexedDB, I don't like the current implementation and have some plans to improve it.

Thanks for pointing out the bookmarks, I totally missed it while I was working on it. I'll look into it.
