After a Network Attack where the Proxy Server was enabled, disabling it still leaves page components missing with "Declaration Dropped" in Error Log. What other setting was changed?

A fake security program claimed corruption, and when it was
deleted it left both FF and IE with the Proxy Server enabled.
When the Proxy was disabled, IE works but FF is failing to
display many page components. Warning in the Error Console have
problems with some HTTP text and then "Declaration Dropped".
What other setting has been changed?
Is there a log of Changes to the Settings?
Shouldn't Changes being confirmed?

cor-el,
>...>Resetting all the parameters back to their defaults cleared the problem, but it did '''NOT''' point out which setting was changed to cause the problem. (It is like picking up some of those bed-bugs and then burning down your house to get rid of them.)
>...>The "master-reset" also does not save a copy of what the setting were so all the problems solved in the past by a settings change will have to be revisited. If it doesn't make a ''prefs-<n>.js'' file, it would have been nice if you would have mentioned it, so one could have been made manually.
>...>The other advice you give would only be helpful if the agent changing the settings was still present. Which it was not. Clearing all the Cookies means alot of re-entry of info for sites using them properly. So you shouldn't recommend it when there is no indication of an on-going problem. And certainly not without warning of the consequences.
You seem very active on this site, but you have not defined any contact information. Are you a developer? If not, are these problems monitored by them? Are do we have to go to MOZILLA.ORG and submit information there?

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.

Cannot find the proxy server even after following the advice in the help section

I successfully downloaded the latest version but I cannot connect to the internet. I get a "cannot find the proxy server" prompt. I have followed the advice in the help section but nothing seems to work.

You can check20the connection settings here:
*Tools > Options > Advanced : Network : Connection > Settings
If you do not need to use a proxy to connect to internet then select "No Proxy" if the default "Use the system proxy settings" setting doesn't work.
See "Firefox connection settings":

It will sometimes work, and then after I shut it down, and then it does not work again. It says it is the proxy server.

The proxy server is refusing connections
Firefox is configured to use a proxy server that is refusing connections.
It worked this morning, and now it is not working. It keeps doing this me. It will work, and then when I go to get on it again, it no longer works.
* Check the proxy settings to make sure that they are correct.
* Contact your network administrator to make sure the proxy server is
working.

Thank you, so much! That worked!!! I appreciate your help.

Where are the proxy server configs?

hi, i use java desktop to configure the proxy server, but now thsi desktop`not work and i use cde desktop, but i nedd to change proxy settings, �where i forund this files to make the changes that i need?
thanks

hmm, normally you just need to put a $http_proxy and $ftp_proxy in the .rc file of your shell;
for tcsh; add:
setenv http_proxy http://my.proxy:8080
for ksh/bash:
export http_proxy http://my.proxy:8080
or
export ftp_proxy $http_proxy
note that its normally small leltters, i think this should work.

"Safari can't connect to the proxy server"

Hello again...
My 10.6 Server is up and running! thanks for all the help...however...
When I try to access the internet via Safari from the actual server, I get the "Safari can't connect to the proxy server" message" but all the client machines can successfully access the internet....
I'll start to read up on proxies but if someone can offer a suggestion in the meantime, that would be terrific. I know it's something simple I am missing...
thanks!

No snarkiness taken Mr. Hoffman...As a full-time high school teacher, I've been setting up our small school server on my own time for the past three months...with the help of the server docs, manuals, and the great help found within this forum, we are finally to a point where we can begin using the server.
What I'm just not understanding is WHAT proxy do I use? I see all kinds of proxy servers out there but is there a specific one I should be using?
Again, forgive me for my ignorance on this matter...I just don't understand why after a year of not using a proxy server, all of a sudden we need to have one? And this issue came about when Safari was unable to "connect to the proxy server"...

When IT folks (or parents) are looking to monitor or control or track network access.
up to this point I don't believe we were using a proxy server?
2) A proxy "regulates" what traffic is passed between machines?
A proxy can enforce access, or can cache access, yes.
So no proxy in effect means traffic goes unchecked between computers...?
Correct.
do we HAVE to use a proxy server with the server?
3) Where does a proxy take effect? At the Router/Gateway? The Server? or >individual machines?

Enabling a proxy server on the snow leopard server should help us out...but again, which address do I use? (in the server doc you referenced, it had "proxyserver.apple.com:8080")but I think that was just the format to use...
Without intending any snark, read the manuals? Servers are big and complex >and expect an understanding of much more than the client boxes do; that's the >inherent difference between "server computing" and "client computing", after >all.
I'm definitely appreciating how much involvement and understanding it takes to get one of these set up...and over the past three months, we've come a long way...
again, thanks for the guidance and help!

There is a problem with the security certificate of the proxy server. Error code 18 and 38.

Hi All,
After several hours and a short night of sleep I'm out of ideas and hopefully someone here can help me trying to solve this one. First of all the situation:
Exchange 2013 on a remote location with a CA-certificate.
Outlook 2010 and 2013 on different locations, locally installed and on RDS.
When I open Outlook on my laptop all is fine, no errors, good sync, no problem. But when I open Outlook on our Remote Desktop Servers with Outlook 2013 I'm getting errors like "There is a problem with the security certificate of the proxy server. The
name on the security certificate is invalid or does not match the name of the site. Outlook is unable to connect to this server. (Error code 18)". Opening Outlook 2010 the message is the same, but the error code now is 38.
After this Outlook opens and is working, there's one more error though. After a while an security warning pops up with the message: "Information you exchange with this site cannot be viewed or changed by others. However, there is a problem with the
site's security certificate. * The security certificate was issued by a company you have not chosen to trust. View the certificate to determine whether you want to trust the certifying authority. * The security certificate is valid. * The name on the security
certificate is invalid or does not match the name of the site."
Strangest thing is, it is the certificate of my RDS! It isn't my valid en officially bought certificate from my mailserver. What's going on? I'm out of options, what I've tried so far (in random order):
- restarting mailserver and AD;
- restarting switches;
- restarting routers;
- restarting RDS, AD and all other servers;
- bypassed proxyserver for RDS;
- created a new profile;
- checked recently installed updates;
- checked certificate on mailserver;
- checked RDS on a different location, working fine.
Nothing helped, what can I do next? Please advice.
Regards.

Found a thread that solves half my problem (https://social.technet.microsoft.com/Forums/office/en-US/70d18244-889a-4d95-ac3f-e234672a82b2/there-is-a-problem-with-the-proxy-servers-security-certificate-error-when-starting-outlook?forum=exchangesvrclients).
The first message can be suppressed by adding this to the Exchange config:
set-outlookprovider -Identity EXCH -CertprincipalName msstd:webmail.domain.tld
set-outlookprovider -Identity EXPR -CertprincipalName msstd:webmail.domain.tld
Giving the command get-outlookprovider, gives me empty information regarding the certprinipalname. Filled
this and after recreating the profile or deleting the ost-file I still have the second alert with the local certificate of my RDS.
Not completely where I want to be, any help regarding the second alert is greatly appreciated!

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.

Proxy Problem The proxy server is refusing connections

I run Windows XP. I did have a Cybot backdoor Activity attack intercepted by Norton Internet Security and I used the Norton NPE to remove it from the computer. I do not know if this caused the proxy problem or not.
There is no proxy problem connecting to the internet through Internet Explorer just through Mozilla Firefox.
When Mozilla Firefox tries to connect to the internet I get the following message:
Firefox is configured to use a proxy server that is refusing connections.
Check the proxy settings to make sure that they are correct.
Contact your network administrator to make sure the proxy server is
working.
In Mozilla I click Tools, options, advanced, network, settings. Under settings Proxy is set on manual, it says that there is no proxy for the figures typed in.
So I click auto detect proxy and I then can connect to internet through Mozilla, however when I log out of the internet, the same proxy server issue is recreated.
What should the Proxy setting be?

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"

Problem loading page, error the proxy server is refusing entry

My computer crashed a week ago, with numerous viruses. After it was fixed, when I go into Firefox, the screen I get is Problem Loading Page, then in a dropdown box it says the proxy server is refusing connection. Cannot get into the internet. What can I do?

In Firefox 3.6.4 and later the default connection settings have been changed to "Use the system proxy settings". 
See "Firefox connection settings" in [[Server not found]]
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

Consistant error message, "The proxy server is refusing connections" What to do now?

"The proxy server is refusing connections"
I believe the update caused this error EVERYTIME I open up firefox. I already know how to disable it since I looked it up. I went to Tools> Options> Advance> Network> Settings> and then the four options including "No proxy" which I've chosen so far. I have tried all four options (except manual, because this causes the error), and every one, but manual, solves it. But my real problem is that every time I close and open up firefox again, the option resets back to "Manual proxy configuration" and I have to choose "no proxy" again.
I opened up Safari to see if it works, and it does work. I think only firefox is affected with the error. I also tried re-installing firefox but didn't work.

Well, the problem is no longer there.. I don't know what I did, and I don't even think I did anything after giving up and waiting for an answer. But here's what is on user file: user_pref("yahoo.homepage.dontask", true);user_pref("network.protocol-handler.warn-external.dnupdate", false);"
Now I have a different problem.. My firefox no longer looks like the way I customized it before. It's bare and minimal.. not too sure if this is the default look, but that doesn't bother me much. The prob is after that changed, I can't seem to view youtube or dailymotion videos anymore on firefox. Video viewing is working on Google Chrome, however. It asked me to update my adobe flash player to view, but I already did. What should I call my previous problem? And should I post this new problem in a different thread?

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.

ITunes 10.5.3.3 "You must log in to the proxy server" error

Hi,
I recently upgraded my iTunes to v10.5.3.3 running on a Windows 7 machine at work. I have had no issues with previous versions, but this new version occasionally gives me the error below:
I can start iTunes without a problem, when I go to the store and start browsing I see this error, but not all of the time. Around 80% of the time when clicking a link in the store I see this error.
My guess would be that the problem arises from network security. Perhaps this new version of iTunes will not pass user name and password to our proxy server. I believe that our proxy will not allow anonymous requests. Presumably something changed wiht the latest update to iTunes.
This issue is stopping me from using iTunes in the way that I would like and I would appreciate any feedback on how I could resolve the problem.
Regards
Ben Lait

Hi
As per the information and details provided by you, to connect the Outlook to the proxy server, please follow these steps: -
This issue may occur if one or more of the following conditions are true:
The connection to the server requires a certification authority (CA).
You have not trusted the certification authority at the root.
The certificate may be invalid or revoked.
The certificate does not match the name of the site.
A third- party add-in or a third-party browser add-in is preventing access.
I hope this information will be helpful for you.
Thanks and regards
