From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; m17) Gecko/20000807 Netscape6/6.0b2 BuildID: 2000080712 I used the following code to write content to an IFRAME: window.frames.content.document.write("services content"); window.frames.content.document.close(); This works great, except that the history object does not advance, so the back button will not work. I don't know if w3c recommends that it should, but I do. Reproducible: Didn't try Expected Results: The new content in the IFRAME should have had it's own place in the history object so that a user can navigate using the back button to the previous content. I haven't tried out this bug with normal frame's document objects, or any other instances of the document object.

Browser, not engine. Reassigning to History component for further triage -
