Currently if I choose a page from the history that was generated by a POST action or hit back when the page has expired results in a messagebox asking me if I want to repost the values. It would be nice if mozilla could tell me something about the page the data came from and the page that is being refreshed. I was thinking something in the line of: ------------------------------------------------------------------------------ The page you're trying to view has expired and was generated by a POST request. etc etc... Originating page: title: "Search form" url: http://page uri Target page: last title: "Search results" url" http://page uri This will give a better idea if it is a good idea to repost the page. If the originating page is title "Customers" url: http://host/customers.html and the target page is: title "Delete action succesful" url: http://host/deletecustomer.html [ YES ] [ NO ] ------------------------------------------------------------------------------ Then I probably don't want to do this again, but there would be no way to know from the dialog.

Note bug 288462.

The login page is getting expired when ever I try to enter

Tentatively moving to Bookmarks & History

I think this is in shared Places code. Moving.

Places doesn't store history for POST pages (they are filtered at the docshell level)

So the bug should be moved to the docshell then?
