Missing Kindle-It button

I installed Kindle-It in Firefox 11.0. No button appeared on my toolbar. I clicked on the link to drag the button to the bookmarks toolbar. No button appeared in my bookmarks toolbar. I don’t even know what the button is supposed to look like, since I can’t find a picture of it anywhere in your support site. What am I doing wrong?

Hi Bonnie, I’ve attached a screenshot showing what the icon looks like. It should appear on your navigation toolbar, not your bookmarks toolbar. If you still don’t see it, please try uninstalling and reinstalling the extension. Let me know if that fixes it for you.

Looks like the attachment is not visibly. Try this: http://help.fivefilters.org/customer/portal/attachments/45066
