Firefox doesn't prompt to authenticate proxy settings

After entering my proxy settings, I am never prompted to enter my login info and thus nothing loads but Firefox's "Unable to connect" error page. I've tried restarting with addons disabled (safe mode), but still no luck.

Ah - if you've set the proxy in Windows, make sure you tell Firefox to use the system proxy. You can do that in the [[Advanced settings for accessibility, browsing, system defaults, network, updates, and encryption#w_network-tab|Network settings]].
*Open the options window: Firefox > Options
*Select the Advanced panel and then the Network tab.
*Click the Settings button.
*Make sure "Use System Proxy settings" is selected.
If that still doesn't work, there could be a problem with your profile. The quickest way to get a fresh profile (while saving your bookmarks, history, passwords, cookies and form data) is to use [[Reset Firefox – easily fix most problems|Firefox Reset]] .
If you don't want to commit to resetting Firefox (it will remove you add-ons and not save your open tabs), you can create a second profile to use for testing this fix with the instructions here - [[Use the Profile Manager to create and remove Firefox profiles]]

PowerShell 4.0 ISE doesn't use the system proxy settings

I can retrieve the contents of a URL using something like 'iwr
http://www.adobe.com' in the command-line PowerShell host.
This takes into account the proxy settings in Control Panel / Internet Options.
If I attempt the exact same thing in the PowerShell ISE, I get:
iwr : The remote name could not be resolved: 'www.adobe.com'
This works only if I add the -Proxy and -ProxyUseDefaultCredentials options.
How comes?
How do I fix this?

I hate to say, but I don't understand how what I see is compatible with your statement.
Let me show what I'm experiencing with more details.
Here's what I get without any proxy options from powershell.exe:
PS 4.0 ~> $r = iwr http://www.adobe.com
PS 4.0 ~> $r -eq $null
False
PS 4.0 ~> $r.GetType()
IsPublic IsSerial Name                                     BaseType
True     False    HtmlWebResponseObject                    Microsoft.PowerSh...
and here's what I get from the ISE:
PS ~> $r = iwr http://www.adobe.com
iwr : The remote name could not be resolved: 'www.adobe.com'
At line:1 char:6
+ $r = iwr http://www.adobe.com
+      ~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-W
   ebRequest], WebException
    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebR
   equestCommand
PS ~> $r -eq $null
True
If the CmdLet requires the -proxy option, how do you explain the results I get without the option from powershell.exe?
Next to that, here's what netsh reports:
PS 4.0 ~> netsh winhttp show proxy
Current WinHTTP proxy settings:
    Direct access (no proxy server).
This is not what I have under "Internet Options", where "Automatically detect settings" and "Use automatic configuration script" are both checked. But IIRC from the proxycfg.exe days this reports the "system-wide"
proxy settings, not the per-user proxy settings.

Why is it that every time I start Firefox I have to fix the proxy settings in the connection area of options?

Every time I start Firefox I have to click on Tools, go to Options, then under the Connections tab select settings and change the proxy to "no proxy" from "Manual Configuration". Why is this doing this?

Firefox switches proxy settings each time a new window is opened

Hello folks!
I'm having a curious problem with Firefox 18.0 since the last update.
Every time I open Firefox or a new application, the proxy settings are set to "Use system proxy settings".
Here's a screenshot of how it looks like right after I opened firefox. In the background you can see the message I now always get, "Unable to find proxy server".
I always have to change this back to "No proxy" to surf the internet. This setting is kept until I open the next window or close and re-open Firefox, than it's reset back at this again, an opening websites does not work.
I first had the idea that the ProxyFoxy-AddIn is causing that, but the problem still exists also after disabling ProxyFoxy.
I'm not sure if this is a Firefox bug or another problem. Maybe can anyone tell me where to set "system proxy settings" in Arch Linux, so that I can avoid this problem. Or do I need to contact Mozilla in this case?
Thank you!
Jan

I think there might be a bug in FF18. After the upgrade, I would also get the error message and couldn't open any site, though using "No proxy" worked I believe. Turns out I had something set under network.proxy.socks (and network.proxy.socks_port) (leftovers of tests done a while back) and even though they shouldn't have been used (I believe, FF17 didn't & I'm using "Use system proxy settings") they obviously were, leading to the problem.
Just resetting those 2 options fixed things for me, and I didn't have time to look into it more, but there might be a bug in there somewhere...
Maybe try checking under about:config if you have any proxy settings set (that you don't need/use) (You don't seem to have any set, but I can't recall if they were visible in the Preferences window or not for me...), and if so reset them. Or just look for any (network) options not using its default value... (Assuming, as it did for me, that running FF18 with a brand new profile works fine.)

VPN Proxy Settings With Third Party Software

Im just wondering if this is possible. When I go to university I've setup a VPN connection and inside of that I've put proxy settings for the available protocols. HTTP, socks, etc.
Well all software built into os x (itunes, safari) use these proxy settings automatically when connected to the VPN. So when I go to uni I click one button to connect and that's it.
What Im wondering: Is it possible for third party software (Firefox, IRC clients) to grab these proxy settings from the VPN? At the moment I'm having to manually add the proxies to these apps every time I go to uni, then disable them when I go home.

Many users have found Authoxy to be the solution for most proxy issues.

[Solved]Gnome 3 global proxy settings not working

Hi
My laptop runs Arch and I use it at a hostel and University. Both have different proxy settings and I had configured it by using a script (if one can call it that) in {/etc/profile.d/} that exported the correct settings. I had to edit (comment/uncomment) my setting every time I mover my laptop.
I need the setting globally for Chromium to pick it up. Chromium until recently had a problem when accessing the Gnome 3 network (proxy) settings. A new update seem to have fixed this but the problem of picking up the setting remains.
I started up a terminal to see how that global proxy setting in Gnome 3 were shown and found that only the following were set
https_proxy
all_proxy
ftp_proxy
The main one that I need {http_proxy} was not set, even thought I defined it. I think this is an issue with Gnome 3 and was not sure where I should report it. Any solutions will be much appreciated.

I've had issues lately with Gnome 3 and proxy settings. For example, as of today (or sometime this weekend) Firefox is not obeying the system proxy settings (System Settings -> Network -> Proxy). Even better was that today I found that the system proxy settings had "magically" reset to proxy.company.com:8080 (or whatever their default setting is). If I manually set Firefox's proxy settings, it connects just fine. All terminal applications that I use only obey the http_proxy environment variable. Other programs, such as Evolution, seem to not obey the Gnome system proxy settings but only the ones set in GConf (not DConf) (which were also "magically" reset today).

Locking proxy settings in Firefox 6? doesn't seem to work the same as 5?

Trying to lock down the proxy settings so users can't disable the proxy. Did this in 5 by editing the firefox.js file in omni.jar then creating a mozzila.cfg file, but same technique doesn't appear to work in 6.
Any ideas what's different?

This does not seem to apply to Firefox 6. I cant locate a place to configure all user settings like there was in the previous versions of Firefox. My Scenario is-
Terminal Server on 2008 R2 and trying to configure all user settings that will apply to all users launching Firefox from the TS.
All documentation and references I have found after an exhaustive search all reference FF 4 and before. Any thoughts?

I use the proxy settings add-on in Firefox to access my company server. However, I updated Firefox this morning to the latest version. Now this add-on doesn'tl.

I used the proxy settings add-on to access the company server and wi-fi with my Android 2.36 phone.
This morning I updated Firefox. The add-on doesn't work anymore. I uninstalled it and went to the add on website to reinstall what I thought must be a new version. This add-on doesn't seem to exist anymore.
How do I change proxy settings with the new version of Firefox for Android?

The author of the add-on will need to update their version to be compliant with our newly rewritten Firefox for Android product.
The new version of Firefox does not provide a user-interface for manipulating proxy settings.
On the other hand, you can manipulate these settings yourself at your own discretion by visiting the URL about:config and searching for network.proxy

When I open firefox it says something about proxy settings! how do i fix this so I can start using it again

It won't let me do anything! All it says 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 clicked the button to reload or whatever and nothing happens just the same old thing over and over!

Check the connection settings.
*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":
*https://support.mozilla.com/kb/Firefox+cannot+load+websites+but+other+programs+can
Start Firefox in <u>[[Safe Mode]]</u> 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).

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.

Removing firefox proxy settings does not work until a restart?

When I transfer from my work network (with a proxy server) to my home network (no server), I have to restart the browser before it realizes that there is no proxy server that it has to authenticate with. Until I do this, (re)loading pages gives me an error.
However, when going the other way, it smoothly recognises that there is a server, and no restart is required to continue browsing
I have automatic proxy settings enabled. I have tried selecting 'no proxy server', but I still need to restart firefox for this to work.

Please update to the current Firefox 22.0 release.

Flash Plugin not using Firefox's proxy settings

Hello there
after observing that we cannot watch some videos (for example
<
http://www.adobe.com/products/flex/media/flexapp/>
or <
http://news.zdnet.com/2422-13569_22-204568.html>)
behind our company's proxy and firewall, I talked to our network
admins and they showed me that on some websites (not YouTube or the
like) it seems like the Firefox Flash plugin doesn't use the proxy
settings from Firefox but rather tries to directly connect to the
respective server, which of course times out. Using Internet
Explorer works perfectly. Has anyone had this problem and knows of
any work arounds or fixes?
Hope someone an help me/us.
Greetings from Germany
Michael

I am facing a similar issue with the flash content on my website (appnina.com). Any flash content is not displayed on my website.
The problem is because of using flash plugin in Mozilla Firefox (21.0 - updated). The flash plugin does not get activated by default. That is whenever opening the site, the flash content is not displayed. It asks to click the activate button. This activation should be one time, however it always asks to do so whenever opening the site.
I just checked and found that this flash problem is not specific to my website but in general (youtube as well).
Let me put the screen shot of the same.
Any permanent solution to this. Let me check if I can delete the old plguin and download it again to solve this issue.
The problem seems to be because of compatibility problem of firefox with flash.
PS: Let me know if I need to start a new discussion thread on this ?
