Firefox cannot load websites but other programs can

Firefox cannot load any webpages, but IE can.
I have tried everything suggested. This problem happened befoer I updated Firefox and did not resolve after I updated firefox.
I tried changing internet settings, disabling firewall, and even disabling IVP6, but nothing is working.

Have you already seen [[firefox cannot load websites but other programs can]]
*What exactly happens, or does not happen and do you get any error messages ?
*Is it all websites you have a problem with, or only some ?
* What happens if you work offline, can you load web pages that are saved on your own computer ? (save something with IE, -as HTML web page files - maybe this page, then try opening it with both Firefox and IE)
Can you use firefox to look at your local disk such as (depending on your setup) ''file:///C:/''
Try checking security settings, and security logs, is firefox being blocked ?

Firefox cannot load websites, but other programs can. Listed guide/faq not effective.

I went through the FAQ guide for firefox not loading webpages, but after having changed both boolean setting in the about:config section of the firefox advanced settings, deleting and re-adding it to the program permissions list in my firewall (mcafee antivirus 2011), and even attempting to completely disable the firewall for a period of time, I am still unable to browse the internet on firefox. Internet explorer, however, does work.

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Firefox cannot print in color a websites but other programs can

The webpage, http://www.rosarysunday.com/seatingchart.html
will not print in color in either Firefox or Seamonkey.
It will print in color from Internet Explorer.

Firefox cannot connect to internet yet other programs can!

Whenever I load Firefox 3.6.7 It doesn't connect to the internet. It constantly says "Unable to connect" however, other browsers such as Opera, I.E, Chrome, these work, also same for Firefox 4.0 Beta 1 too.
What is the problem?
== This happened ==
Every time Firefox opened
== Few hours ago ==
== User Agent ==

Just so we're clear, when you say "I've tried all the tips" are you referring to the [[Firefox cannot load websites but other programs can]] article?

I Can't load a website but other people can, it's not a problem with their website, I Can load any other page besides this website.

I've been trying to get on this website for the past two days, All other websites work fine for me but this one doesn't, all other people I've asked have been able to get on it just fine, but I have not. It's not just on Firefox either, Internet Explorer and Google Chrome cannot load this website for me.

Do a malware check with some malware scanning programs. 
You need to scan with all programs because each program detects different malware. 
Make sure that you update each program to get the latest version of their databases before doing a scan.

Firefox cannot load websites but other programs can. I followed the problem solving steps, however I can't access to any web site.

I followed the following step (in spanish):
Configuración de la conexión para Firefox
Si te conectas a Internet a través de un servidor proxy que tiene problemas de conexión, no podrás cargar páginas web. Para comprobar la configuración del proxy de Firefox:
1.En la parte superior de la ventana de Firefox, en la barra de menú, haz clic en el menú Herramientas, y selecciona Opciones....
2.Selecciona el panel Avanzado.
3.Selecciona la pestaña Red.
4.En la sección Conexión, haz clic en Configuración... .
5.Cambia la configuración del proxy:
◦Si no te conectas a Internet a través de un proxy (o no sabes si te conectas a través de uno), selecciona Sin proxy.
◦Si te conectas a Internet a través de un proxy, compara la configuración de Firefox con la de otro navegador (como Internet Explorer. Consulta Guía de configuración de proxy de Microsoft) (O Safari. Consulta Guía de configuración de proxy de Apple).
1.Cierra la ventana de Configuración de conexión.
2.Haz clic en Aceptar para cerrar la ventana de OpcionesHaz clic en Cerrar para cerrar la ventana de preferenciasCerrar la ventana de preferencias

You need to allow for the loopback connection in Firefox, as an "outgoing" connection.

Why cannot Firefox 8 load websites but other programs can?

Using Win XP there are URL:s which doesn't work at FF 8 but open in Internet Explorer. My friend using Win7 and knows a lot of computers tested same URL:s and told me there's a bug in FF8. When I write for example www.tarjanompelimo.com in address bar or use any links including that URL browser goes to empty index-site but should go to http://www.tarjanompelimo.com/main.htm. In earlier versions of Firefox there hasn't been any problems and it's still working in Internet Explorer.

Firefox cannot load websites but other programs can (link to solution is dead)

Firefox either takes a long time to load some pages or simply does not load them, ever. I've just tested it and tried in IE9 to load one of those pages that FF never loads. IE9 loaded it immediately. Browsing through your FAQ pages, i found a question about this problem, but when i click it, it turns out the link is dead

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
You can try to decrease the value of the pref network.http.max-connections from 255 to a more modest setting like 30 as used in Firefox 3 versions.

All help posted for Firefox cannot load websites but other programs can fail, now what?

I have tried all the things listed but they made no difference at all.
I have no problem with IE. I have been to this site before and it is a bookmarked site.
This problem only came with the last update that never saved any of my search engines either.
Can go to some sites but not others and I have been there before.
Is it time to dump Firefox?
EDIT: One of the sites is speedtest.net, how crap is that?

Big FAIL there as well. I have already tried all that.
I also ran Moz Backup and that failed to help.
I can google speedtest but when I click on the result in the search it times out.
If I try from my bookmarks it also times out.
I have about 80 bookmarks I use all the time
I won't return to Firefox if this is the crap I get after updates.
Not the first time I have had to start from the beginning.
Why do they release this crap if it is not ready for us to use?
I have already tried all the things listed as well as increasing the time out period. That just took longer to tell me it had timed out. RUBBISH

Firefox cannot load a specific website but other programs can

I have a rare problem with firefox (3.6.18 at the moment)
I have to work with a modified mantis bug tracker and the site wont load (the tab says "Loading..." and the bottom status bar says "waiting yourdomain.com...")
I can reproduce this and seems to be related to the cookies: I have a page with a big image still loading, I submit a form from this page and that is were the problem happens.
From here no page from this bug tracker will load.
This only happens to me with firefox and not with other browsers.
If I clear the cookies, the site will load again.
Hope you can help me
Thanks, Fernando.

You can try to load that page in Private Browsing mode.

In PB mode Firefox doesn't use the disk cache and the cookies from normal mode.
