1) (optional) start with a clean, new profile 2) start the browser 3) Type http://www.mozilla.org/ in urlbar and hit enter 4) Check the listing under the Go menu item 5) Type http://www.cnn.com/ in urlbar and hit enter 6) Check the listing under the Go menu item 7) Type http://www.mozilla.org/newlayout in urlbar and hit enter 8) Check the listing under the Go menu item Actual results: everything is fine until 7&8; after /newlayout is loaded, the history for that window has been erased. The Go menu shows only the current page in the list, and the back button is disabled The key event here is _leaving_ http://www.cnn.com/. (The choice of the other two urls was just to have two very vanilla pages). The problem has something to do with the content on that CNN page (and presumably how it affects the firing of notifications). This worked in 9/21 win2k trunk, but is broken in 9/23 win2k trunk. I see that there was a checkin for session history in the period of time on the trunk. "Fix for bug 92824. Update index in session History only after onStartLoad notifications come for the page. r=adamlaock sr=rpotts" The cnn page does a lot of js 'document.write("<IFRAME...', sort of tricks. If you disable JS in Navigator, then this problem (unsurprisingly) goes away. (NOTE: this is _not_ on the 0_9_4 branch!)

and bug 105299 - they're all the same bug i think

Yes, this would appear to be bug 103978. I'll let radha mark it as a dup. I just want to restate that the sequence above is reproducible 100% in 9/23 and later builds, but not in a 9/21 trunk build (on win2k). I think it is related to the checkin that happened 9/21 for session history (although perhaps this bug only became apparent due to some later change in the CNN content).

> and bug 105299 - they're all the same bug i think That bug concerns the 'location.replace()' method. Note: in the content that is served by www.cnn.com to mozilla, there is _NO_ occurence of 'location.replace()' in any downloaded file.

*&%*@# nsbranch?, nsbeta1? ... why are we (re)using such lame, generic keywords to track product targets. What's wrong with nsmachv?

This is dupe of 103978. This bug is present in 0.9.5, but not in the trunk right now. However there are few more issues at cnn's site right now due to expired pages and CSS initiated reload of a iframes. I'm working on them. Please see 103978 for more info. *** This bug has been marked as a duplicate of 103978 ***
