Ask HN: Looking for tool that adds links to Wordpress from Firefox

I browsed around the WordPress plugins page, but couldn't find this tool: When I come across a page that I find interesting, I'd like to be able to click an icon in Firefox that adds a link to the page on my blog. That way when people visit my site, they can see my recommended sites. Preferably, I'd like this to be a section in the sidebar (do not want a new post every time I submit a new link). Currently, to do this, I have to copy/paste the URL into the the theme editor - which is a pain in the ass. Does something like this exist?
