You should remove this:
HTML Code:
<base target="_blank">
from your page and see if it helps. That might be all you need to do but there could be other problems. If that fixes it and you still want that base target, you could try adding a target to the bookmarksite link:
HTML Code:
<a target="_self" href="javascript:bookmarksite('Free Top Keywords', 'http://www.freetopkeywords.com')">
or
HTML Code:
<a target="" href="javascript:bookmarksite('Free Top Keywords', 'http://www.freetopkeywords.com')">
But, you may need to drop the base target and add individual targets to each link where desired.
