Iceweasel proxy setting - does this mean I don't need proxy server?


I am using Iceweasel with debian wheezy. I have thought about using a proxy server for anonymity on the net.
However, on the Iceweasel Advanced Settings, it shows that there is a proxy setting already being used.

Does this mean I don't need to use a proxy server if I use Iceweasel?
Can anyone please advise about linux methods of preserving anonymity?

Using a proxy doesn't give you anonymity - all data passes via your ISP (and various spying agencies).
You need to pay for a VPN and communicate via an encrypted tunnel.
It helps if the VPN is located in a foreign country.

Even then, your ISP (and spying agencies) can see that you are using a VPN (via traffic analysis).
So you probably need to be something like using TOR or Tails https://tails.boum.org/.

You don't need to use a proxy in iceweasel if you don't want to.

Thank you.
I read a little about tails and may look into it more.
So it seems Iceweasel does use a proxy - this is ok for me as long as it keeps analytics companies at bay.

How can I tell what proxy isp Iceweasel is using? I just want to confirm it's different from my isp.

Look at how "iceweasel connects to internet" in the configuration.
If it says proxy then it must give a proxy name.

Using the Iceweasel browser, I visited a couple of websites which show your IP http://www.whatsmyip.us/ http://www.whatismyip.com/.

I then opened a terminal and viewed the resolv.conf file which shows my actual IP address.
Code:
user@debian:~$ cd /
user@debian:/$ cd etc
user@debian:/etc$ cat resolv.conf
Since the IP is different - it confirms that I'm using a proxy server when I browse with Iceweasel.
So every time I use the browser, I'm not giving away my personal IP address.

My /etc/resolv.conf reads
Code:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 192.168.1.1
This is identical to the LAN-side (non-internet) address of my router.

The internet sites reveal the WAN-side (internet) address of the router which happens to be 87.114.130.xxx
This is the address allocated by my ISP.

All of this reveals nothing about whether you are using a proxy.

This is interesting.
So how do I know which proxy server Iceweasel is using?
I can't imagine there would be any problem with the server, but usually you can access such information.

If you look at "Configure how iceweasel connects to the internet", you will see a screen like:-

Yes, but the only problem is it doesn't say where the proxy server is located and who owns it.
I'm sure it's an ok proxy server because Debian is responsible for Iceweasel - and I think it's a bit more secure than firefox.
Even so, details of the proxy server would be nice.

Because the "no proxy" button is ticked, all the proxy name fields are blank.

On Iceweasel, I go to Edit-Preferences-Advanced tab-Connection settings. I then select 'Use system proxy settings', because I want to use the browsers proxy server.

However, everything is blanked out. It's only when I select 'Manual proxy configuration' that all the blank fields light up.
I don't want to use a manual proxy server because I don't have one.
So I just make sure that 'Use system proxy settings' is selected.

Even so, Iceweasel doesn't give any info on what the 'system proxy setting' is.
I've looked up the WAN IP address for my pc http://www.whatismyip.com/.
The website shows the details of my actual ISP and says 'no proxy detected'.

So this seems to mean that Iceweasel isn't using a proxy server.
Isn't that correct?

Yes - you have to define your proxy somwhere (either by name or ip address).
See http://en.wikipedia.org/wiki/Proxy_server for what you might want to use a proxy for.

Thank you. That answers my question.

A proxy server will be an expensive piece of hardware which will need maintenance.
So now we need a proxy server which will offer this service for free and ask no questions!
That's the problem with proxy servers in my view. Thank you for your reply.

Where are the proxy settings in Iceweasel

I'm setting up Iceweasel to work with burp and can't find the proxy configuration options.

The documentation for burp says, in part,
Quote:
Firefox - Note: If you are using Firefox and you have the Plug-n-hack plugin installed in Firefox, you can configure your browser to work with Burp automatically. Using your browser, visit the URL of your Proxy listener (as identified above - for example: http://127.0.0.1:8080) and following the "Plug-n-hack" link.
If you do not have the Plug-n-hack plugin installed in Firefox, go to the Firefox menu, click on Options, click on Advanced, go to the Network tab, and click on the Settings button in the Connection section. Select the "Manual proxy configuration" radio button. Enter your Burp Proxy listener address in the "HTTP proxy" field (by default, 127.0.0.1). Enter your Burp Proxy listener port in the "Port" field (by default, 8080). Make sure the "Use this proxy server for all protocols" box is checked. Delete anything that appears in the "No proxy for" field. Then click "OK" to close all of the options dialogs.
I suspect that iceweasel is fairly similar.

I know nothing about burp, so you you should RTFM.
