  • Hi friends, the most of internet users using Mozilla Firefox. As you are on internet there are always many chances to get Hack that nobody wants to. So here is the one step forward to secure yourself from Hackers. Here we are have you ever notice the Private Browsing option in your firefox?  If you didn't so, read this article to know what it is meant for...

     


    First of all you have to understand what is cookies ?
     
    Cookies have, for some reason, gained a rather sinister image. But they really are simple and harmless. A cookie is just one or more pieces of information stored as text strings on your machine. A Web server sends you a cookie and the browser stores it. The browser then returns the cookie to the server the next time the page is referenced. The most common use of a cookie is to store a user ID. For example, the cookie might containg the following string:
      ID=96352398
    ­ Amazon.com is one site that uses this technique. When you order a book, you fill out a form with your name and address. Amazon assigns you an ID, stores your information with that ID in its database on the server, and sends the ID to your browser as a cookie. Your browser stores the ID on your hard disk. The next time you go to Amazon, the ID is sent back to the server. The server looks you up by your ID and customizes the Web page it sends back to you. The page might say, "Welcome back, Joe Smith!"
    You may be wondering:
    • Is there any more to cookies than that? No. They are simply text strings. On my machine there is a directory called c:\windows\cookies that contains all of the cookies. They are little text files -- you can open them up and see the strings that are being saved.
    • Are cookies harmful? No. They are just short text strings, and they can often make browsing better by allowing a server to recall any customized information you have set.
    • Are cookies common? Yes. There are over 500 separate cookies on my hard disk.
    • Can cookies transmit computer viruses? No. They are just text strings.
    • Can a company read my personal information from my hard disk with a cookie? No. Only the cookie that is sent in the first place is returned to the server. It is not modified or manipulated in any way.
    Now i hope you understand what are cookies and what they do.

    Case I:

    Cookies is mostly for storing username and password.  Cookies stored as plain text or Encrypted form.  If you just close the mozilla,cookies won't be deleted(depending on websites,some high secure website will delete cookies when session come to end).  If you visit too many websites ,you may forget to logout.  It is gateway for hackers. Others can steal your cookies.

    Case II

    Sometime you may visit some private websites or blogs whatever.  Others can also view which websites you visits.


    Solution:
    Mozilla Firefox:
    There is two features in mozila for you.  First one ,you may know about that.  Second one, i think people know rarely about that.

    Clear Recent History:

    First one is clear recent history option.  It will available in:

    Tools->Clear Recent History.


    After selecting the menu,you can view the pop up box like this:




     check all option as shown in the image.
    Click "Clear Now" button.

    Second One:Private Browsing:

    In first one ,you have to delete manually history, cookies and others. Sometimes you may forget to clear histories. Those who forgetting problem, second one will be useful. 

    Tools->Start Private Browsing.

     

    If you select the private browsing option, no cookies , history will be stored in your system and all your work will be safe. But you are doing this you will not be able to store Youtube or Facebook videos in your computer without downloading them. Click here to read the full article...
