Why would Firefox not be able to visit Google anymore?

Lately I've noticed that my Firefox Browser was taking a long time when I would search Google, e.g. 3 seconds before I would see any results.

If I search for a three-word phrase, it just hangs trying to connect:

I removed all add-ons but it still does this.

I thought it might be something with my router, but Chrome, Safari, Opera and Internet Explorer all work fine.

Bing works fine in Firefox.

Here's my Firefox version information:

Otherwise I can still use Firefox, e.g. I'm using it to post this question, but I do notice that when I browse with it, images are often "broken" for a split second before they appear, as if it is having a hard time pulling them from a remote server. Other browsers don't do this.

What could be causing Firefox to hang when searching Google?

Does it do the same thing on a different computer? – user541686 – 2011-02-02T05:13:10.203

On a second computer using WLAN with the same router, Firefox works fine. – Edward Tanguay – 2011-02-02T05:19:03.110

Huh, interesting. Have you tried clearing your history (cache, cookies, etc.) by any chance? – user541686 – 2011-02-02T05:23:32.137

Ok, I did tools | clear recent history (which knocked me off this site, had to log back in) but no, search google still hangs. – Edward Tanguay – 2011-02-02T05:31:06.510

You may have added a IP address to your firewall that inadvertantly blocks google services? Which version of Firefox, what OS, what kind of network are you behind, all this information is needed when troubleshooting such a difficult and weird question. – palbakulich – 2011-02-02T05:32:35.617

Firefox on another account on this same computer works fine. – Edward Tanguay – 2011-02-02T05:34:09.800

@Edward: Have you by any chance run Spybot Search & Destroy's Immunization feature? It can cause delays like this... it wouldn't be Google-specific, but it does cause delays for browsers (and even Explorer itself). – user541686 – 2011-02-02T05:35:30.700

The version of Firefox is 3.6.13 (see screenshot above), Windows 7, this is a home network, one router from Deutsche Telekom (Berlin). – Edward Tanguay – 2011-02-02T05:35:32.433

I think this problem coincided with the installation of a DivX software (http://www.divx.com/en/software/divx-plus) and it installs some browser add on, e.g. I noticed youtube videos had an option to use this software. I've tried uninstalling it twice and it is proving difficult to get rid of.

@merhdad I've never used a spybot software just because I assume they are spyware themselves, what can you recommend? – Edward Tanguay – 2011-02-02T05:40:34.800

@Edward: Interesting, okay. Spybot Search & Destroy and Lavasoft Ad-Aware are legitimate antispyware software, but like all security software, they slow down the system in some ways, depending on which features you use. But I can't think of any problem with your Firefox... I'd say maybe try creating a new profile with the -ProfileManager switch to see if that will change anything, but I doubt it will. :\ – user541686 – 2011-02-02T05:55:29.653

Try going to google using their own DNS: 8.8.8.8 and 8.8.4.4. – Zubair1 – 2011-08-19T12:46:40.633

Try running firefox in safemode. There should be a link from when firefox installed. The target in the shortcut is the same except it just has -safe-mode at the end. I have found that malicious plugins or settings can remain even after disabling everything manually. If firefox suddenly works in firefox -safe-mode then there is a good chance that there is a plugin that is not playing nice and will need to be removed by a program like Spybot Search & Destroy , Ad-Aware, super antispyware, or malwarebytes.

Also make sure that firefox is not set up to use any proxy settings. It should be set to "Use system proxy settings" by default.

If it is set to "Use system proxy settings", then check IE's proxy settings. Even though Google works in IE, it is possible that malware has set a proxy for IE (and all other apps that check system proxy settings) that behaves oddly when it sees Firefox. Not likely, but a few extra clicks for something worth checking. – TuxRug – 2011-02-02T06:32:25.973
