Firefox addons

You can imagine that if I could just overwrite any existing information about your IP address I would have done so (or somebody else would have a while back ago)...

But it's actually a little more tricky : when sending a request to a server you will provide several information about your IP address : three of them come from the Application Layer and the last one comes from the Transport Layer. This last one I can't modify : you wouldn't get the answer to your request if that was done. But the three others can be overwritten without any consequence to your browsing...

These three headers were created to provide information on the real IP of a person surfing through a proxy server. So when you enable IPFuck, the websites you are visiting will believe that your real IP is a proxy server and (if the website was done correctly) focus on the false IP you are sending...

A lot of websites try and figure out who is hidding behind a proxy server. And if you don't believe me (I won't mind), just check out this google search request : get real ip address php. Most of the snipplets given here will check HTTP headers (the one we overwrite) before the Transport Layer information ('REMOTE_ADDR').

IpFuck

In short: This addon attributes HTTP_X_FORWARDED_FOR , HTTP_CLIENT_IP and HTTP_VIA to some random or selected IP value, the REMOTE_ADDR being "of course" affected to your "true", vpn or proxy , IP address. So the website you visit think that your "true" IP is a only a proxy IP (what could actually be the case if you already use a proxy to connect to the web, but do not add complications), and that your true IP is one of the 3 random generated IP's.

You can do that yourself via Header Filter. Loved that addon when I used Firefox, and it still comes useful sometimes.

"Header filter" ?? I didn't knew this addon before, and find no trace of it on Mozilla's site

Maybe are you speaking about ModifyHeader ?

I have it and like it, and IPfuck seems to be based on it, but for "ip obfuscation" purpose (presenting your real IP address for a proxy IP, and a faked one for your real IP) , I find Ipfuck more easy to use.

Yes, that's the one - mixed up the name

Funny, that may get your real IP on a blacklist for being a proxy. And that isn't exactly useful either.

Just found, installed and liked this one. Like themes for wikipedia, significantly improves readibility!

Your're right in pointing that.

It's an obvious risk if your own IP is static. The risk is weaker if you use a dynamic IP, or if you connect to the internet through a an IP already known as a proxy.

But in the first case, it may be interesting to suggest that your own IP is not really yours ; and in the second case, the extension may be considered as a tool allowing to transform every proxy in a configurable distorting proxy.

I got access denied using this addon, with no proxy. It has happened just once.

I had to reinstall firefox after a

attack
So the first thing i do after i install FF is to go searching for add-ons...Even those few moments without my favorite add-ons made me uncomfortable...

1.Adblock Plus Pop-Up Addon
FF on it own is a great popup blocker but it can't stop on-click pop ups/unders.This unaffiliated extension of the popular adblockplus does just that
2.Adblock Plus Element Hiding Helper
3.Chatzilla
4.Imagehost Grabber
5.Linkification
6.MultiLinks
7.NextImage
8.Profile manager and synchronizer
9.Profile Switcher
10.QuickRestart
11.Screengrab
12.ShowMeMore
13.Tabscope
14.Tinyeye Reverse Image Search
15.WML browser
-----------------------------------------------------------------------------

I didn't include the most commonly used ones like flashblock/adblock/downloadhelper etc. coz almost everyone has them...
These are lesser known and most of them are now defunct(make them functional by changing .xpi file)
I use stumbleupon (or atleast used to,before work started...) a LOT and come across all types of websites and these addons make surfing that much more fun...
