What is proxy settings default?

I'm wondering what is the proxy settings default setting? On my computer it is set to "Use system proxy settings" I'm wondering what should be the default the version of firefox I am using which is the latest version of firefox.

"Use system proxy settings" is the default in current Firefox versions and should work in most cases. 
Only if there are problems then you can try to select "No Proxy".

What HTTP Proxy settings to use and when?

On the Wi-Fi Networks menu there are three options for HTTP Proxy - Off, Manual, Auto
Which one should I use and when/why would I use the others?
thx, gordo

99% of the time, you should have the proxy settings turned off. Unless you are trying to connect to a corporate network, or some other network that requires a proxy server. In that case you would need to talk to the network administrators to obtain the settings you would need. If your just connecting to your wireless network at home, your almost for sure not going to need to enter anything for the proxy server settings.

What are proxy settings for

my pc would not connect to the internet or to mozilla because it says mozilla are using some sort of proxy. i have now turned the proxy off. will this harm anything.

Usually Firefox will connect to the network using your system settings, which you can find either in IE or in the Windows Control Panel, Internet Options, on the Connections tab under LAN Settings.
Firefox ''can'' use a different connection method to take advantage of an intermediary. For example:
* Security software on your PC which intercepts and cleanses your web traffic
* Private VPN service that sends your requests out through a different device so it can't be tracked back to your ISP
However, these settings also could be used by an attacker to divert you away from the "real" internet to one where fake sites can be interposed to capture your passwords or other personal information.
Not sure exactly what is happening in your case, but if you made a note of the earlier settings, that would be helpful in investigating further.

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

I get a message that I ned to check proxy settings. What does this mean?

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.
Contact your network administrator to make sure the proxy server is
working.
I cannot open firefox because I get htis message above. Don't know what to do.

I can't see what version of Firefox you're using because you've deleted that information. So here are the settings for both. 
For Firefox 4.0.x 
* Click the orange Firefox button, go to Options | Options | Advanced | Network (tab) | Settings (button) and checkmark "Use system proxy settings" or "No proxy". 
For Firefox 3.6.x 
* Click Tools | Options | Advanced | Network (tab) | Settings (button) and checkmark "Use system proxy settings" or "No proxy". 
If you choose "Use system proxy settings" which is the default, Firefox connects to itself which provides a certain degree of safety.
"No Proxy" connects directly to the Internet.

Detect default proxy settings

I am creating an applet which needs to get data from the internet. Since the applet will be run behind different firewalls, I was wondering how to detect the default proxy, i.e. the one the browser is using. Many apps I have seen have an option 'auto detect proxy' and I was wondering how to implement this in an applet.
Thanks

you might find that proxy settings are in the registry somewhere; i'd be guessing that's how these apps do it.
as your app is java it shouldn't typically be looking up registry keys, but if it's only going to be running on windows, then .....

What is the keyboard short cut to switch from proxy settings to none

I have a website that requires specific SSL settings and i changed my proxy settings to go there.
But for the rest of my browsing i don't use a proxy.
How do i toggle between without going through Preference Settings? Is there a keyboard shortcut?
thanks!

What are the PROXY SETTINGS (port) for HP Photosmart printer 7520 ???

CANNOT FIND THE CORRECT PORT ( proxy setting ) for my
HP 7520 Photosmart PRINTER???

Hi torino71,
Welcome to the HP Support Forums! I see you would like to know which proxy settings to set for your HP Photosmart 7520. I was able to find a great thread from a fellow Community member windrunner123, see below:
In some network setup, proxy settings may need to be configured on the printer to enable connection to the Internet.
1. Make sure the printer is on a network and must have an IP address assigned by a Network Router or a DHCP server. Alternatively, you may also configure the printer to use a static IP address. Check and retrieve the IP address of the printer from the Home Screen menu selection: Network -> View Network Summary -> View Wired (or View Wireless) or Setup -> Network > View Network Summary (depending on printer model)
2. In a web browser on your computer, type the IP address or hostname that has been assigned to your printer.
3. Go to the Network Tab > Proxy Settings and enter the proxy settings into the fields and click Apply button. You may have to check with your ISP or IT Administrator for the correct Proxy Setting.
As well as the port settings below you will want your router company to make sure that multicasting is enabled, bonjour protocol needs to be enabled, make sure that mac filtering is disabled, and have them check if there are any firmware updates for the router, and check firewalls on the router to make sure not blocking the communication
The following ports are also used by your HP device and might need to be opened on your firewall configuration
Incoming ports (UDP) are destination ports on the computer while outgoing ports (TCP) are destination ports on the HP device:
Incoming (UDP) ports
137, 138, 161, 427
Outgoing (TCP) ports
137, 139, 427, 9100, 9220, 9500
The ports are used for the following functions:
Printing
UDP ports 427, 137 161
TCP port 9100
Photo card upload
UDP ports 137 138 427
TCP 139
Scanning
UDP port 427
TCP 9220, 9500
Faxing
UDP port 427
TCP port 9220
HP Device Installation
UDP port 427
Web Services
80, 443, 5222 and 5223

When I bring up Firefox it asks me to make sure the Proxy Settings are correct. What are the proxy settings?

When I double click on the Mozilla Firefox icon to open it up an error message comes up and says "The Proxy Server 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.
Please help me with this.
Thank you

Try the following solutions and whichever setting works, keep it Permanent:
1) go to Tools Menu -> Options -> Advanced -> Network -> click "Settings..." button infront of Connection -> select option1 -> Click OK -> OK
2) go to Tools Menu -> Options -> Advanced -> Network -> click "Settings..." button infront of Connection -> select option2 -> Click OK -> OK
3) go to Tools Menu -> Options -> Advanced -> Network -> click "Settings..." button infront of Connection -> select option3 -> Click OK -> OK
Check which solution works.

Why or how could firefox change my proxy settings without me doing anything right in the middle of browsing the internet?

== Issue
==
I have another kind of problem with Firefox
== Description
==
While I was browsing the internet suddenly nothing would happen when I clicked a link. Upon closing and opening firefox and trying to load a web page it said "the proxy server is refusing connection. Firefox is configured to use a proxy server that is refusing connections."
I did manage to fix the problem by changing the proxy settings from manual to auto-detect but what disturbs me is how those settings could be changed without me doing so right in the middle of using the internet. I dont know if its a bug or a security issue but I thought I would let you guys know.

Strange info in "Bypass Proxy Settings for These Hosts and Domains"

For my Mac Mini my Network IP Address always has a self-assigned 169.254 number that I cannot change. Strangely, this same IP number is similar to info that is in the Proxies section (of Network Settings) under "Bypass Proxy Settings for These Hosts and Domains".
No matter what I do, this info (*,local, 169.254/16) appears in my Network Settings in the Proxies section under "Bypass Proxy Settings for These Hosts and Domains". (I tried removing the info and it would cause the "Configure Proxies" selection to default to "Always Use PAC File". Had to go back and retrash all the plist files to have Proxies go back to "Configure Proxies-Manually". Still, the info (*,local, 169.254/16) continues to appear in the "Bypass Proxy Settings for These Hosts and Domains" section and my IP address is always a 169.254 number.)
Comcast cable modem via direct hardwired Ethernet works fine with my other computer, so not the modem. Also, other computer does not have any info in the "Bypass Proxy Settings for These Hosts and Domains" section.
Installed a fresh copy of OS X 11.5 on a new hard drive. Still the same problem.
I posted this issue before but only got one responder and the problem still exists. Any clues? Somebody must know about this stuff. Help please.
Thanks

When your Mac wakes up, it does not yet have an IP Addresss. It wants to send a request to a Router for an apprpriste IP address to use now. But it needs to have an IP address (like a return address) to receive any messages. So, ... wait for it,
... it (your Mac) makes one up. There are rules that ensure it is a random address, but they always start with 169.254. It is on the same subnet with any low-order 16 bits This is the "self-assigned" range of IP Addresses. This address is only good for talking on a local network segment, for things like asking for a valid IP Address from a DHCP-enabled Router.
In most cases, on most networks, the 169.254 self-assigned IP Address is replaced by a valid Local IP Address such as 192.168.xxx yyy or 10.0.xxx.yyy so quickly that you never even see the 169.254 Address.
If you do see the 169.254 Address, it can be read as "Nobody will talk to me" or "Nobody will give me an IP Address". When you have this IP Address for more than an instant, you should suspect bad cables for Ethernet connections, bad signal strength or interference for wireless, Router configuration problems, or Mac configuration problems.
Mac configuration problems are often solved by using the "Assist Me" button is System Preferences > Network and choosing to set up again.
Another diagnostic is to try using Network Utility and the Ping function, and Ping-ing the address of your Airport base Station, often 192.168.0.1 or 10.0.0.1 or similar. This will tell you if the Router is reachable, or there are cabling/wirelss signal problems.
In this case, proxies are not an issue, and are simply a distraction from the real problems.

Use System Proxy Settings - when this is selected in FF v3.6.6, does it adhere to the same local IE proxy setting? We use a pac file configured in "Use automatic configuration script."

Does anyone know what Firefox looks at locally on the PC when the "Use System Proxy Settings" setting is selected? It appears to be the default setting, recently changed from "No Proxy" of versions past...
Our company uses a pac file specified in IE under "Use automatic configuration script" - with this new default, does it adhere to the same setting in:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]

I may be wrong but I think that the "Use System Proxy Settings" makes sense only on Linux and generally speaking "other OSes". As far as I know there is no generic proxy settings in Windows operating system.
The one I know is in the registry part of Internet Explorer.
So in my understanding in Windows, Use System Proxy Settings = No Proxy

Firefox proxy settings with OD users

I need to add a proxy setting to firefox on 50 OD bound clients, firefox being the annoyance that it is doesn't pickup the sys prefs settings, anyone know how I can add the proxy setting remotely via WGM perhaps?
thanks in advance

Hi
Firefox keeps its settings in /Users/Home/Library/Application Support/Firefox/Profiles/mixofnumbersandletters.default/prefs.js. This file does not lend itself too easily for use in Workgroup Manager's Preferences Manifest.
What you could do - which is what I sometimes do - is to configure the Proxy Settings first on one client workstation. You could do this either one of two ways; keying about:config in Firefox itself or simply amending the Network Settings. This should 'write' the relevant information you want. Copy the prefs.js file to the Desktop. Quit out of Firefox and delete the User's Firefox Profile from the Application Support folder. Right click or Control Click on the Firefox application itself and select show Package Contents. Drill down through the Contents folder to the MacOS folder. Keep on going through the defaults folder. In there you should see a profile folder with an existing prefs.js. Overwrite this with the one on the Desktop. Now re-launch Firefox. Any user (local or otherwise) will receive those settings as default as they are set by the Application rather than by the User.
All you have to do now is copy the Firefox application to all of your clients. Which you could a number of ways. Copy the application to a pencil stick or CD and walk round each client in turn and copying the amended Firefox Application to the Applications folder. Or use the Copy command in ARD. Or prepare the client workstation you did this all on as a NetRestore Image and image the remaining workstations.
