User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5a) Gecko/20030711 Mozilla Firebird/0.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5a) Gecko/20030711 Mozilla Firebird/0.6

Every "Destination" page on this site does this in Mozilla Firebird, as it did
in Mozilla. Whenever I try to access one, the page does not finish displaying
and reloads constantly.

Reproducible: Always

Steps to Reproduce:
1. Go to http://www.courrierinternational.com/voyage/00-voyage.htm
2. Choose any destination in the "Destinations" drop-down menu.
3. See the bug in action.

Actual Results:  
Page reloads, and reloads, and reloads.

Expected Results:  
Mozilla should load the page once and display it.

If it does it in Mozilla as well, it's a Browser bug.

Do you allow cookies from this site?

Comment 3

[Marc-André Descôteaux]

Boris --> I have no restrictions whatsoever on cookies, nor on images or
Javascript. I tried with pop-up windows allowed, to no avail.

Comment 4

[David G King]

Confirming with Mozilla 1.6b and a different URL, in my case
http://hfnetchk.shavlik.com/support/hfpro4help/hfn.htm

Both my, and the example URL use Javascript rather a lot, which is where I
suspect the problem is.

Comment 5

[Boris Zbarsky [:bzbarsky]]

David, any chance of a minimal testcase?  In the future, please do NOT confirm
bugs like this without a minimal testcase....

Comment 6

[David G King]

I should have thought of that. Testcase coming....

Comment 7

[David G King]

Attachment: Minimal testcase

This is the root of the problem. The IF statement tests conditions which are
set in the 3 external JavaScript files. In all 3 cases the variable is set to
TRUE at the very end of the included JS file.

Comment 8

[David G King]

Just been doing some testing. I changed the testcase so that the 3 external
javascript files were no longer external (quick copy & paste).

When I do that, the javascript works fine and gbWhVer, gbWhUtil & gbWhMsg are
all true. When left as external files, gbWhVer is true, and gbWhUtil & gbWhMsg
are both undefined.

Now, I'm not a Javascript guru, but shouldn't it matter if the Javascript code
is in the html file, or "included" from an external file?

[Boris Zbarsky [:bzbarsky]]

Hmm.. When I load http://hfnetchk.shavlik.com/support/hfpro4help/hfn.htm with
mozilla trunk nightly 2003-12-14-08, all three vars are defined (and "true") and
there is no looping.  There is also no reloading in the same build on
http://www.courrierinternational.com/voyage/Articles/AME/cl01-240702.htm

Comment 10

[David G King]

I've just checked with a local build from this morning NZDT, and I get the same
problem. What OS are you using with the 14/12 trunk build?

Comment 11

[Boris Zbarsky [:bzbarsky]]

Linux. Sorry, thought I said that.  :(

Comment 12

[David G King]

I've just tested Mozilla 1.6b on Fedora Core 1 Linux, and hit the reloading problem.

I'm now building a more current version to see what happens.

Comment 13

[Boris Zbarsky [:bzbarsky]]

This could also depend on profile settings, I suppose.  I was _not_ testing with
a vanilla profile....

Comment 14

[David G King]

Just got the same behaviour from a fresh build of Mozilla on Linux. Changing OS
to ALL.

Comment 15

[Boris Zbarsky [:bzbarsky]]

David, can you test with a vanilla profile?  I'll try to get my hands on a
Mozilla build again and do the same.

Comment 16

[David G King]

OK, you were right in comment #13, this seems to be a profile issue, at least
for my testcase.

I created a new profile, using Mozilla 1.6b, and the page loaded (although it
seemed to be doing a lot of repainting as it loaded different parts of the page.
Once the page is in cache, it loads no problem. I even tried changing from the
default "classic" theme to the "modern" theme, but that didn't break it.

The courrierinternational site still reloads, and gives me lots of popups.

Comment 17

[David G King]

I just tried Firebird v0.7 to see what it does. Got the same results as with
Mozilla and a new profile.

I'm going to cutdown the other example URL to find the core problem that it has.

Comment 18

[David G King]

Hmmm, the courrierinternational site contains interesting HTML.  Nested BODY
statements for example "<BODY>blah blah<BODY>blah blah</BODY>blah blah</BODY>".

I'm going to keep trying to reduce it to see if it is another example, but I
think it has other problems.

Comment 19

Attachment: courrierinternational min testcase

OK, got the courrierinternational site down to the essential problem (ignoring
the invalid HTML).

What is happening AFAIK is that a Javscript function called "taille()" is
called, which seems to drop down and rerun itself....I assume if I left it
running long enough it would use up all memory and crash my PC.

Comment 20

[Boris Zbarsky [:bzbarsky]]

Well, that code basically does:

if (browser is IE) {
  // do something
} else if (browser is NS4) {
  // do something
} else {
  // set location to the current page location, causing page to reload and this
  // script to run again
}

It wouldn't use up all your memory, because that last part is async.

In any case, this is evang -- any browser that implements neither
document.layers nor document.all would loop on that site.

Comment 21

[Boris Zbarsky [:bzbarsky]]

Note, though, that what I said only applies to browsers whose appVersion
includes the string "Win" or the string "Mac" (which Mozilla on Linux typically
does not).

Comment 22

[Marc-André Descôteaux]

The "Courrier international" website has been redone, and the reload no longer
occurs. Should this bug be closed, or at least renamed?

Comment 23

[Paul van Schayck]

It can be marked FIXED.

I have developed my site (https://whatsgroupslinks.com//) and facing the same issue while logging into mozilla. I still confused about how can I take this or solve this issue.
