Keep getting "Proxy server is refusing connections, check proxy settings

I downloaded Firefox and I keep getting ..."Proxy server is refusing connections. Check proxy settings." What are proxy settings and where do I find them?

The default "Use the system proxy settings" setting doesn't always work properly on Windows XP and in such a case it is better to select "No proxy".
You can find the connection settings in Tools > Options > Advanced : Network : Connection

When I try to open Firefox, it says that "the proxy server is refusing connections." What settings do I need to change? Even though the internet signal is strong, I can't open any webpages.

It also says that Windows cannot connect to the Internet using HTTP, HTTPS or FTP. This is probably caused by Firewall settings on this computers. Check the firewall settings for HTTP port (80), HTPPS prot (443) & FTP port (21).
This all started when I tried to tried to delete the Verizon Broadband toolbar and home page that always opened when I opened Firefox.

In Firefox 3.6.4 and later the default connection settings have been changed to "Use the system proxy settings".

I can't get online through firefox (this keeps coming up THE PROXY SERVER IS REFUSING CONNECTIONS) but can through internet explorer?

As I said in the question when I click on the firefox link on the desktop this is what comes up (THE PROXY SERVER IS REFUSING CONNECTIONS Firefox is configured to use a proxy server that is refusing connections) but I can get connected through Internet Explorer. I have uninstalled firefox and reinstalled firefox with no difference.

I tried all that stuff and none of it helped. I can't load any of the google applications in firefox now. They pop up with this screen.
This Connection is Untrusted
You have asked Firefox to connect securely to mail.google.com, but we can't confirm that your connection is secure.
Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.
What Should I Do?
If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.
mail.google.com uses an invalid security certificate. The certificate is not trusted because it was issued by an invalid CA certificate. (Error code: sec_error_inadequate_key_usage)
Now I tried a couple of other sites and they all seemed to work okay, and if necessary I could click understand the risks and still access the site, but no go with google. Considering I use my google account for my calendar and gmail a lot, I am highly disappointed with this new update. I hate using IE and really prefer to use Firefox.

Keep gettig this error message when trying to connect to Firefox The proxy server is refusing connections.

Redownloaded Firefox and continue to get this error message when trying to connect: The proxy server is refusing connections
Firefox is configured to use a proxy server that is refusing connections.
Check the proxy settings to make sure that they are correct.

Not related to your question, but...
It is important that you keep IE updated. The information included with your question, indicates that you are using IE7; you should update to IE8 for your own protection. IE9 will not be made available for Windows XP.

Suddenly get message: Proxy Server is refusing connection. How do I fix to access the Internet as before?

Had no problems getting on the Internet until about a week ago. Then suddenly when I tried to click on a website, I got this message: "proxy server is refusing connections"; however I have no proxy server when I go into My Computer and check under proxy server. I have tried uninstalling Mozilla Firefox and then downloading the new 4.0--which did, indeed, install.
Yet, when I clicked on the icon, I got the same old message.
How can hook back up to the browser so that I can go back online and access internet websites?

If you do not keep the "No Proxy" setting then see:

Whenever I try to go to a website I get the following message: The proxy server is refusing connections. How do I fix this?

My web proider is Verizon Fios. I've contacted Verizon 4 times about this. I was instructed to delete Firefox and then download again. It didn't help. I'm able to get to your main window. Then, when I try to go to any website, the following window comes up: "The proxy server is refusing connections. Firefox is configured to use a proxy server that is refusing connections. It tells me to "Check the proxy settings to make sure that they are correct." I tried that w/ my Verizon support person but how is one to know what "settings" are "correct"? Finally the window instructs: "Contact your network administrator to make sure the proxy server is working." Who would my "network administrator" be? It wasn't Verizon as they told me they don't support Mozilla.

Everytime I receive an email with an address for the main content, all I get is the following statement "The proxy server is refusing connections" This happens evrytime and is very fraustrating.

When I click onto the "Read Full Article..." tab I go to the Mozilla Firefox page which says there is a problem loading page - Mozilla Firefox, and then get the "The proxy server is refusing connections" and the o2 Broadband assistant then kicks in and starts trying to find the connections even though o2 broadband is connected.
I have tried re-installing Firefox but this does not improve the situation which is frustrating as I have to send everything to my work account so that I can read any further information.

Updated to firefox 3.6.6 on laptop and now it can't acces the net "The proxy server is refusing connections" I've restarted twice. My other computer in home works fine. Just not laptop on Network/WiFi

Can't access the web on lap. It's networked form main computer. The problem started just after I downloaded/updated to Firefox 3.6.6. That may be a coincidence. I get "The proxy server is refusing connections". Restarts don't help. My main computer is fine. I didn't update it.
== This happened ==
Just once or twice
== just after an update to 3.6.6

Firefox 3.6.6 made a change in prefs to use system proxy settings.
Check your proxy / network setting in Windows and change it to No Proxy, if you don't use a proxy.

please try if it's the same when you launch firefox in safemode once (then it might be an issue with an extension hiding this setting) or else try a reset of firefox.

Unable to open any website due to The proxy server is refusing connections, why?

Firefox is opened, but unable to open any website. The message says, "The proxy server is refusing connections" & "Firefox is configured to use a proxy server that is refusing connections". I installed the version 8.0.1 again. But there was the same message, again!

Trying to use with TOR - 'Proxy Server is refusing connections' but TOR is connected.

Added TOR button to Firefox. It could be a TOR problem, but the TOR control panel shows it as connected. When I make TOR enabled and try to go to a website, I get the 'Proxy Server is refusing connections' message.

"Proxy server is refusing connections" error message, fixed with Network Settings but won't save my preferences. Have tried everything!

I always have to go
Firefox>Option>Network>Settings>Select Auto-Detect Proxy
Every time I open firefox.
I read the "Preferences Not Saved" Help but I don't have a User file in my Containing Folder, so I couldn't change that.
Deleted my prefs.js files, but when it automatically made a new one it was still stuck on "Manual Proxy Settings" which leads to the "Proxy server is refusing connections" error.
Any new ideas? Please?

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.
