Reproducible: Always Steps to Reproduce: 1.Middle-click in a page (even a blank page will do) 2. View the dom (with the generated source bookmarklet for example - http://www.squarefree.com/bookmarklets/webdevel.html) or save the page. 3. Actual Results: The generated source shows the img code for the autoscroll-icon. The saved file would also show that same source code. Expected Results: It should not show that code. The auto-scroll feature is browser-specific.

Sorry, I´m just seeing this is probably a duplicate of 215762

I'd doubt it's a duplicate, but since we already have specific info like this shown in the DOM Inspector (select an element, switch to Javascript Object view), specifically the all-caps NS* functions, this is probably WONTFIX. Unless we actually DON'T want this showing to the outside, perhaps because it's part of the chrome and foreign Javascripts are supposed to run in a sandbox that wouldn't affect the chrome...

Same cause as bug 215762, bug 215825, etc.
