Rated 4 out of 5 stars

In Firefox's View—>Toolbars—>Customize… window, the icon doesn't look normal, it looks like the back, forward, refresh, and stop buttons all in one icon, and with no text to indicate what it is. When I mouse over it the word "feedly" appears, and that's the only reason I knew what it was. It appears normal in the toolbar itself, though.
