[TYPO3-english] problem with ex. Bookmark-Extension ( toi_bookmarks )

[Tim]

I have a problem with installation of this extension.
In typo3 I create a page where add a plugin (bookmark-center). This page is
protected, only view for FE user.
When open this page, show:

In TS I add this code:
page.9000 < plugin.tx_toibookmarks_pi2
page.9000 < plugin.tx_toibookmarks_pi3

But I don't see button for bookmark pages. How work this extension?
Is this extension working with RealURL?

Best regards,
Tim
