Description Mark Polo 2010-04-23 17:08:25 UTC
Description of problem:
I access the Internet through a CheckPoint firewall (some form of hardened Red Hat Linux). For the past few weeks, certain websites are no longer accessible from Firefox on Linux (although they are accessible from Firefox on Windows, Opera on Linux and from "telnet URL 80" on Linux).

Version-Release number of selected component (if applicable):

How reproducible:
Attempt to access www.youtube.com or www.easyjet.com (probably others, those are the two that are presently causing me grief) from behind the CheckPoint firewall. Other websites work without problem.

Steps to Reproduce:
1. Enter address into address bar.
2. Press enter.
Actual results:
FW-1 at AL-NHU-ALEMANIA: Access denied.

Expected results:
Access to the website in question.

Additional info: I realize that this is a pretty esoteric problem. However, the fact that the sites work from Opera and from Firefox-win32 would seem to point to a problem in Firefox rather than in my network. If you need more information, just tell me what you need.

I have already tried firefox in safe mode (firefox -safe-mode), and the problem persisted. Other connectivity is normal to these sites (ping, nslookup, telnet www.youtube.com 80).

I have solved the problem. I had IPv6 disabled, and apparently it needed to be enabled. As such, I am closing my bug report.

Comment 2 Mark Polo 2010-04-24 21:33:43 UTC
Well, that's embarassing. I was able to make precisely one connection after making that change, and after that, Firefox returned to its usual behavior. As mentioned, the problem first occurred a few weeks ago.

Comment 3 Mark Polo 2010-07-23 16:39:42 UTC
The problem has now proven to be local (our firewall was refusing long requests, and Firefox seems to send a longer user agent, and so was going over).

This can be closed.
