When I relaunch firefox 8 the proxy server settings reset back to Manual even after I change to autodetect

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.

Current 3.6.3 version works fine on my laptop; however, when i download the update version, 3.6.4, it will download but i can't open any internet sites and firefox says it refuses the proxy server settings, which never changed during the download

when mozilla opens up automatically after download, the message that the proxy server settings are refused comes up on the opening mozilla screen. it also says it cannot recognize any websites that i try to load.

It just won't connect to the server
never had this problem

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.

All proxy server settings in mac lab deleted possibly after a firefox update? How can I recover settings without manually doing on all machines?

Most (if not all) of my lab machines have lost their proxy settings...weird...has never happened before. Because the settings were in firefox, I assume it is because of a recent firefox update. First...is there any way to revert back to the previous settings so I don't have to manually reconfigure all users on all machines. Second...please make sure that this doesn't happen again when updates are implemented. Third...does anybody know anything about pushing out a proxy setting through ARD?

Sound like a corrupted or deleted file prefs.js in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder]

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.

I would like to upgrade my firefox but when I do it cannot find the proxy server

When I try to up grade to the new firefox 5.o from the 3.5 I currently have it cannot find my proxy server and I do not know how to fix this

In current Firefox versions the default connection settings are set to "Use the system proxy settings".
You can find the connection settings in Tools > Options > Advanced : Network : Connection 
If you do not need to use a proxy to connect to internet then select "No Proxy"

I received a message to upgrade my Firefox , when I upgraded to Firefox 6.0.2 it says (The proxy server is refusing connections .) I had a copy of Firefox 3.5.5, which works fine.

When I try to connect to the web using the larest version of firefox, it tells me the Proxy Server is refusing connection. When I reinstall an earlier verion it seems to work fine!!! What's the Problem?

Downloaded Latest version 3 6.?? .12
Next time I tried to connect to the Web the Proxy server refuses connection & tells me to reconfigure my settings.
I reinstalled the older version, which worked OK, then uploaded the latest version again & it does the same thing when I log off & try to reconnect!

My Firefox no longer works, it will not go to any website and offers the message "The proxy server is rejecting connections". I had the same problem in IExplorer but was able to fix it. I did not choose a proxy server, ever. How do I fix this in Firefox?

I changed out my wireless router, from a Linksys to a Netgear. Everything seemed to work fine, but shortly afterward Firefox could not be used to find any websites, and gave me the message above. The same happened with Internet Explorer, but a tech representative for my ISP directed me to the page where "proxy server" was incorrectly checked and it fixed the problem. I don't know where to go in Firefox to find the same or a similar page. My laptop continued to work fine for some time after, but eventually developed the same problem. I uninstalled and reinstalled Firefox, with no luck, and all desktop shortcuts based on Firefox are inoperative. I just keep getting the message that the proxy server is rejecting connections. Since I did not select a proxy server, I don't know how to deselect it.

No idea what "tried everything" means.
Here is how you troubleshoot a password problem.
Go to your email providers web mail page and verify that you have a working username and password by logging into your account there. If you cannot log in there, look for the link to reset your password. Your email password is administered with your email provider.
Once you have a working password you need to remove any stored passwords in Thunderbird and replace with the new, working password.
From the menu bar select''' Tools-Options-Security-Passwords-Stored Passwords'''
Remove the passwords for the problem account. Close Thunderbird and restart it. You will be asked for a password. Enter the new password.
No menu bar with Tools? Press the '''alt '''key.
FYI: Thunderbird settings are stored in a different file from the program. Removing the program and reinstalling just keeps you busy for a little while and rarely fixes anything. As you have seen the old settings are picked up when Thunderbird is reinstalled.

Message "the proxy server is refusing connection" pops up when connecting to wi-fi

When I go to connect my other dell laptop to the wireless internet, the message (The proxy server is refusing to connect" comes up. it says further, "Firefox is configured to use a proxy server that is refusing connections." Cannot figure out how to (re-configure?) firefox so that I can log onto wi-fi...

If you do not need to use a proxy to connect to internet then select "No Proxy"

What do I do when it says "The proxy server is refusing connections, etc"?

Att.net is my home page. I have long used Firefox. When I click on the att.net icon on my opening page, this message pops up:
The proxy server is refusing connectons.
Firefox is configured to use a proxy server that is refusing connections.
* Check the proxy settings to make sure they are correct..
* Contact your network administrator to make sure the proxy server is working.
I have no idea what this means since I am not PC proficient. I have had to returen to Internet Explorer which is not as satisfactory as Firefox was.
If a reply is sent, my only request is that it be kept simple.

To: cor-el
A thousand thanks for your help. The"No Proxy" check didn't work, so I fooled around with the other selections until "Use System Proxy Settings" did the job. I'm grateful.

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.

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.

I have Mozilla Firefox installed, but whenever I try to bring it up I get a message that says "The proxy server is refusing connections" What do I do?

This is what follows the first statement;
"Firefox is configured to use a proxy server that is refusing connections".
*Check the proxy settings to make sure they are correct. (Done)
*Contact your network administrator to make sure the proxy server is working.
I have called COMCAST, my internet service provider and they said there is nothing they can do for me.
I would appreciate an answer to this problem

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 
If you do not need to use a proxy to connect to internet then select "No Proxy"

Firefox keeps requesting logon credentials for the proxy server, though they are eneterd in the connection settings.

Every time you go to a new page, Firefox prompts for the proxy server login credentials, this has already been entered in the Network settings in Firefox.

Hi thefrostycat,
It could also be the proxy set up on the network. There is an app for proxy settings: [https://play.google.com/store/apps/details?id=com.lechucksoftware.proxy.proxysettings on the play store] as well as an add on [https://addons.mozilla.org/en-us/firefox/addon/proxy-selector/?src=search Proxy Selector]
Android troubleshooting for GSM device(I do not know if your nexus is, most likely it is not): Access Point Name (APN). Go to Settings > Wireless and Networks > More > Mobile Networks > Access Point Names > [Your data APN] (your device's menu may differ slightly). Check the Proxy field.
