Can You Get Pregnant With A Cervix Erosion

Surf anonymously using Firefox

1 .- Hide IP our

This application will install the trio Tor & Privoxy & Vidalia . From this link is can download and install the 3 applications together through a single file if you use Windows, or by following a few simple steps if you use Linux . The default settings should work, which only have to run the program. What is that doing? It creates a network of connections around the world, and makes our web page requests go through the computer network, hiding your IP address and our geographical location. Obviously this will slow down our connection a lot, but it will not be a problem because in the same package you install a plugin for firefox, which will add a button on the bottom right to toggle Internet connection through the network so that only we use when we needed. In theory, the installation of this plugin should be automatic, but I needed to do it manually, from this web . Finally, tell them that you can configure almost any program you have, and connects to the Internet, to do so by TOR.

NOTE: This description of TOR should be taken as an approximation to what really is this technology ( onion proxy.) There is a formal description, but a simple explanation so that everyone can understand without much knowledge. For more precise and technical, you should resort to project documentation.

2 .- Hide our AGENT in your browser

When your browser visits a website, offers information, consisting of a string. The Firefox has the following form:

  Mozilla /   MozVer    (    Platform;     Security;  subplatform   ;     Language; rv:   
Review [; Extension ] * ) Gecko / GeckVer [Product / ProdVer ]

It shows the browser you use, the operating system and other things. Using the plugin for Firefox Agent-Switcher can change these settings at will, saying for instance that we ...

The indexer robot google :

Mozilla/5.0 (compatible; Googlebot/2.1; + http://www.google.com/bot.html)

A portable playstation :

Mozilla/4.0 (PSP (PlayStation Portable); 2.00)

Or a Wii:

Opera/9.10 (Wii; U;, 1621; en)

Or any other combination of operating system, browser and language. I tell you, that if we do go through the google bot, we have certain deificultades to perform advanced searches in google.

3 .- Change request headers specifically

When asked for a web page, your browser transmits some information that would normally not see. Are the http headers, and this is an example of such headers from Firefox browsing and asking for google homepage:

Host = www . google.es
User-Agent = Mozilla/5.0 (Linux)

Accept = image / png ,*/*; q = 0.5
Accept-Language = en-us, is, q = 0.8, en-us; q = 0.5,, q = 0.3 Accept-Encoding
= gzip, deflate Accept-Charset
= ISO-8859-1, utf- 8, q = 0.7, *, q = 0.7 Keep-Alive

= 300 Connection = keep-alive Cookie
= PREF = ID = 159a53d47b27436e ...

To observe these headers, and any particular change, we can use the Firefox extension Tamper Data. Not particularly useful in terms of anonymity, but in relation to what some sites can learn from us. This utility is designed for testing servers, but might be helpful to some Conspiranoids.
