I'm a Pinboard user accustomed to bookmarking webpages using their bookmarklet, which looks like this:

href="javascript:q=location.href;if(document.getSelection){d=document.getSelection();}else{d='';};p=document.title;void(open('https://pinboard.in/add?url='+encodeURIComponent(q)+'&description='+encodeURIComponent(d)+'&title='+encodeURIComponent(p),'Pinboard','toolbar=no,width=700,height=350'))

Of the privacy Tor provides me as I'm browsing the web, what, if anything, would I be giving up or risking by using a bookmarklet like this?

I know not disabling javascript in the Tor browser is itself a risk, so I suppose I am asking what added or specific risk am I taking with this bookmarklet...
