Tabs and Javascript buttons

I'm trying to get del.icio.us to work since I updated
multizilla/mozilla (both current now). The only way it will work is if
I disable opening new tabs entirely for all bookmarks/personal tool
bar. That defeats the main reason I use multizilla so I'm not sure
what to do next.

The problem exists in SeaMonkey too, which I am now switching to (and
having the same problem with).

The post button for del.icio.us is javascript:
javascript:location.href='http://del.icio.us/pinktaffy?v=3&url='+encodeURIComponent(location.href)+'&title='+encodeURIComponent(document.title)

I tried a couple of other javascript links and any that need to grap
the url from the current tab fail because the button is just opening
up in a blank tab. Not sure how to work around this problem.

Sorry if I make little sense or am missing something easy. I'm tired.
