754700 - Page does not load completely unless referred to by a link

Status: UNCONFIRMED

(Firefox :: General, defect)

Description

[alberthrocks]

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:12.0) Gecko/20100101 Firefox/12.0
Build ID: 20120420145725

Steps to reproduce:

I tried to go to a website, wolframalpha.com. I've experienced this problem before with other websites, but don't remember which.


Actual results:

The page does not load completely.
(see http://pastebin.com/61NneBnY - dump from View Source)


Expected results:

The browser should have loaded the whole page.

Other browsers work fine, like Chrome.
I've tried clearing all of my data, but the problem still persists. I do not use any proxies, and my firewall is obviously not interfering since Chrome can download the whole page.

Does this happen for you in the latest Nightly? nightly.mozilla.org
Does this happen every time you go to wolframalpha?
Does this happen if you run with a new Firefox profile? firefox.exe -P
Are there any errors in the Error Console?

1) Yes, up to date.
2) Yes, I created a separate profile for FF5.
3) There's one error, related to an incomplete JS download.

This is from a clean install of FF5 nightly.
The source is pretty much the same as before (I didn't check for any changes)

FF5 Nightly, or Firefox 15 Nightly?

Firefox 5 is woefully out of date.

Heh, I meant Firefox 15 (downloaded from nightly.mozilla.org). Sorry about that!

This also doesn't work: (only the first "Premium" image shows up, and no DL link)

Sorry, I'm not able to reproduce this at all. Nightly, Beta, and Release all show wolframalpha.com and the link in comment 5 without any issues.

I know you said earlier that you don't think your Firewall has anything to do with it because it lets Chrome through. However, I'd like you to try shutting off your firewall and testing again; just to remove it from the equation.

I'm running a stock Windows XP with a completely new Firefox profile so there has to be something (either configuration or software) that is causing this issue. That doesn't mean it's not a Firefox bug, but we need to identify what might be interacting with Firefox to cause this problem.

Interesting... I've disabled all of the firewalls, and nothing changed. HOWEVER, when I disabled (or actually, uninstalled) the other "firewall" - to be specific, Norton Online Family - everything started working again! So I guess you'll have to complain to Symantec to work with them to fix this issue.

Note, however, that a good 99% of the world probably doesn't have this installed, and their problems could be caused by different programs (which may be fixed from this bug).

(By the way, I removed Nightly because it was interfering with the regular version, and other people ran into Nightly instead of the stable FF. Nevertheless, this behavior still can be reproduced on the regular FF.)

Thank you very much for checking into this; CCing Kev Needham.

Kevin, do we have contacts at Symantec you could reach out to?
