124213 - Back button does not work correctly

Status: RESOLVED DUPLICATE of bug 83684

(Core :: DOM: Navigation, defect)

Description

[[e-mail]]

Seeing this with 0.9.8 release (2002020415/linux, 2002020406/windows) 
and nightly 2002022602/linux:
1) Go to some web page (e.g. www.mozilla.org).
2) change the url to www.derstandard.at
3) click on one of article links in the middle/center frame 
4) click the back button or select the back function from the
   context menu

expected result: the previous page should be shown
actual result: the previous page is not shown, but the 
next to previous page (www.mozilla.org) is shown.

I have the same problem in build 2002012508.

I still see this with 2002030521/linux - can anybody confirm?
I think that back button should finally work correctly in the 1.0 release which
is branching quite soon.

Hmm I just retried with 2002040211/linux.
I did this a couple of times and sometimes it worked and
sometimes it didnt. 
The problem seems to be this: if the initial page of 
www.derstandard.at is not completely, fully loaded
before you click the next link, the back button seems 
to skip the page when going back. When I made sure that 
I clicked the article link while the page "www.derstandard.at"
was still loading (throbber active), I could reproduce it 
every time.

I currently see this bug with 0.9.9 on win2k.
This bug annoys me nearly daily since at least two months.

A:="bug appeared", B:="initial page was fully loaded".
I do not see any correlation between A and B.
I just tested a little and saw all 4 combinations: A&&B, A&&!B, !A&&B, !A&&!B.

Creating a reduced testcase seems to be difficult, since the site uses a lot of
javascript.

I dont say that it doesnt happen when the page is fully loaded, just that
it was easier for me to reproduce it on the given server when it is not.
I remember though, that it also happened what the page was seemingly 
fully loaded. Could it be that some loading is not indicated by the throbber?

Robert, have you seen this on any other site too or just this one?

Comment 8

[Robert Pollak]

No, I have not seen this bug anywhere else yet.

BTW, I have also noticed that sometimes the initial page seems to be fully
loaded, but the throbber does not stop spinning. But I think this is a separate
bug - an instance of bug 39310.

Back button is not working.  The back button does not "rise" when there should 
be pages in history.  The URL bar displays the initial URL typed in, even after 
having used links in the page.  History does have items in it for the session

I see the problem. Shall look into it.

Deleted Mozilla.org dir (win2000) and reinstalled (I was using rc3), back and
forward now OK.

83684 descries the same problem at this website. Seems to have more testcases too.
