There's no builtin feature that allows you to print bookmarks, but it can be done. If you export your bookmarks to an HTML file, you can open that in Firefox like a regular website. If you want to see the URLs on the page, you can press F12 on the keyboard when the page is open, select the console tab and paste the following code into the textbox next to the >> symbol: <pre>var d=document,sS='a[href^="http://"]:after, a[href^="https://"]:after {content:"<" attr(href) ">";padding:0 0 0 1em;} a[href] {text-decoration:none;}',nS=d.createElement('STYLE');nS.setAttribute('type','text/css');nS.innerHTML=unescape(sS);d.getElementsByTagName('head')[0].appendChild(nS);</pre> Then you can just print it like a normal website page.
