Changing Favicon?

[Empress_Swanbottom]

I made my own favicon and used filezilla to delete the original and put in my own, but it won't change in the tabs; it still shows the original one. How can I make it change?

(and yes, I have it named favicon and its filetype as ico just like the original)

Well sometimes it takes a while for the new favicon to show up, especially on Firefox.

Okay, hopefully it'll be changed before long. :)
This is what I'm trying to make it-
