Just to clarify, what is happening when you click a result link: nothing happens at all?

However, if you disable JavaScript (about:config => javascript.enabled => false) then it works normally?

Do you notice any difference if:

(1) You disable "instant prediction" results here: https://www.google.com/preferences (login not required, this is stored in a cookie)

(2) You are logged in versus logged out of your Google account?

By the way, if you want to disable JavaScript just on one or two sites and leave it enabled for all other sites, you can use this extension: https://addons.mozilla.org/firefox/addon/yesscript/

FYI,

when I click a result link : nothing happens at all, as in picture it buffers for 10 mins showing connecting, after some time, it shows "Connection was reset try again".

And BTW if I disable Java script in about:config, it only works until the next restart of browser.

When I tried to change the Google preferences & save as shown in picture, it buffers for 10 mins showing connecting, after some time, it shows "Connection was reset try again" and it is throwing error that "your cookies seem to be disabled", but as shown my cookies setting is fine.

Do you want to try one of the extensions that blocks Google's click tracking? As you can see in the third screen shot, Firefox is stalling on Google's /url script. The following extension (and there are others) bypasses the script so you can go to the result site more directly:

https://addons.mozilla.org/firefox/addon/google-redirect-rewrite-remove/

Note: I haven't tested it myself.

Does that help?

I'm puzzled about Google saying your cookies are not enabled. However, it is possible to create a site-specific exception. To check that, click the padlock or globe in the address back, then More Information, then Permissions. If you scroll or scan down the list of permissions to Set Cookies, you can see whether Google is blocked.

Still No result.

Does DHCP server has got to do anything with this problem ?

Google normally routs the result link to their safe browsing testing service via an onmousedown event that modifies the link (href attribute) if you click it once.

You can check if this bookmarklet makes a difference:

javascript:(function(){var e=document.querySelectorAll('#search a[onmousedown]'),E,i;for(i=0;E=e[i];i++){E.removeAttribute('onmousedown')}})()

Do a malware check with several malware scanning programs on the Windows computer. Please scan with all programs because each program detects different malware. All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

Still no result. 1. I have checked in my laptop with other ISP connection, it is working fine. only problem when I use my network. What might be the problem with my network ? please go through the the above section for workaround I have gone-through.

Suggest me a solution so that I can find out what is the problem in my network, which is blocking in 2 browsers & allowing chrome.

In your original post, you mentioned disabling Java in about:config. Do you mean switching

javascript.enabled

to false allowed you to use Google normally?

What is your connection setting here:

"3-bar" menu button (or Tools menu) > Options > Advanced > Network mini-tab > "Settings button

The default of "Use system proxy settings" should use your Windows/IE "LAN" settings. You also could try "No proxy".

1. Im using, the auto proxy settings, if i select other options in network, i cannot load even google homepage. 2. yes i have toggled to false javascript.enabled
