Firefox not opening Yahoomail

rajesh.bahl · 07-24-2011, 03:01 AM

Dear experts,

Need your help to sort out the following issue:-

I recently installed CentOS 6 on my PC. So far every thing seems to be OK except net surfing. I have observed that if I try to open some specific sites like:

yahoomail.com
123greetings.com

the firefox browser seem to "hang". At the bottom left corner, it keeps displaying "connected to s.yimg.com".

Almost all other sites seem to be working OK.
I wish to inform that on second hard disk on the same PC has CentOS 5.6 installed and there is absolutely no issue on this.

Kindly help in resolving the same.

Regards
rajesh.bahl

What version of Firefox?

What plugins have you got installed?

Have you tried another web browser? With what results?

Perhaps your firewall is the issue. Maybe if you allow Auth/Ident (TCP port 113) to be permitted, that it would help.

[later edit] I doubt that your firewall is the issue, but I have no other guesses.

1. The version of firefox is 3.6.9 ( the default that comes with CentOS 6.0). THere are no plugins installed - it's plain new installation. I have tried opera - it is opening yahoomail but very slowly.

2. There is no firewall installed. The iptables service is also disabled.

The problem is typical to a few sites only.

Is ipv6 disabled?
Are the DNS servers the same on both OS?
try

Code:

echo 0 > /proc/sys/net/ipv4/tcp_window_scaling

Kind regards

I have just accessed the two sites in the original post using Firefox on CentOS 6 both 32 and 64 bit versions. They seem to load OK. Does the problem happen all of the time? I have had occasional issues of this sort which appear to be Internet issues beyond my system. Do you have another machine on the same LAN or Internet connection which you can try at the same time? This might help to localize the issue.

Another thought... Do you have any preferences adjusted in Firefox? I have only changed Privacy; History; Never remember history. The rest are as installed defaults.

Finally, if you do not find an answer here you might try posting over on the CentOS.org forums.

Hi All,

First of all, I tried repo's suggestion. The login screen appeared. When I keyed in username and password, the browser did not show any further page.

After that I un installed ipv6 from the system.Also disabled ipv6 support in firefox. Now even login screen is also not coming.
Tried reversing the above changes but the browser is not opening the login screen of yahoomail also.

I wish to remind that on the same connection and machine, I am able to open anything if I switch to CentOS 5.6
Any other idea ??

Yes. Exactly same ( working on the same DSl line).

Use wireshark ou tcpdump to see if there is any network latency in DNS(v6), HTTP, ...

A thought - is the date set correctly on your machine? If the date is not set correctly, https sites may send you on a redirect loop.

rajesh.bahl · 08-03-2011, 12:23 PM

Date and time are absolutely correct.

I am not running Cent6 but ScientificLinux 6.1
the default FF works just fine in yahoo mail and gmail

"yimg.com" is mostly the advertising
INSTALL "ad block pulse" and "No-script "

Dear John VV,

I installed Noscript in firefox and tried opening yahoomail.
Firefox was able to show the opening page but not fully ( it opened the home page of yahoomail and offered me to login ).
On supplying the username and password, the screen showed a messagethat my FF settings are not proper to display the next page.

Any further suggestions, please ???

John VV · 08-10-2011, 01:33 PM

well did you configure them ?
add block needs a subscription ,the first restart after installing took you to the web site

no-script needs to be set
the instructions were on the web page ff took you to on the first restart after you installed it .

there is a red circle with a "s" in the lower right corner
configure no-script there .
http://noscript.net/

but the default everything on sl6.1 works just fine for yahoomail
i do not have to set anything for ff 3.6 on sl6

now did you by hand install a different ff like ff5
if so you WILL have problems

now you can update your 3.6.9 to the current 3 ( 3.6.18 )
under the help button you should see "update" or ( new version is available)
on start ff will call home and look
