From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.1) Gecko/20020812 BuildID: 20020812 When I open http://www.mediamarkt.de/redir/shop.mediamarkt.de in a new window and then click one of the links (i.e. "PCs" or "Monitore") then the back button stays grayed out! This also seems to mess up the history: -Go to http://www.mediamarkt.de/ -click "Angebote" , then click "Monitore" -use the back button to go back and then click the the forward button to return to the frame. When you click the forward button nothing happens!

Its because it creates a frameset. The parent window URL does not change. Not only that, but the frameset is created via javascript, which could be the problem.

changing summary for now. I'll try to see if this is a duplicate.

Change summary back. not due to the fact that the frames are generated by javascript document.write(). Not due to the fact that the second page has: <meta HTTP-EQUIV="pragma" CONTENT="no-cache"> <meta http-equiv="expires" content="0"> still need to create a test case

possible duplicate of bug #162593??

Could this be related to bug #126826 or bug #162593?

How about with http://www.ahead.de? Using 2002110610 trunk, back button is completely inoperative on this site.

re Jerry Baker Thank you for the link. I've filed bug 179633 for the problem.
