To protect your privacy on the web, you need to learn about the cookie controls provided in your browser. You should also investigate some specialized tools that can control all cookie types. Unfortunately, however, even if you do make the effort to control cookies, there is little that you can currently do to protect against cookie-less. How to protect your privacy with third party cookies In order to enjoy some of the conveniences of the modern day internet you’re going to have to put up with some cookies. Many sites use third party cookies as a way to boost their revenue, so it’s likely they’ll block you from seeing content until you accept third party cookies.
Cookies
When you visit a website, not only are you offered information or services, but your computer may also be offered a “cookie.” A cookie is a small file that is passed from a website to an end user’s (your) computer, often without your knowledge or consent. The cookie is used to save information about the interaction between you and the site, such as login credentials, preferences, and any work in progress. The cookie file is automatically stored by your browser (e.g., Internet Explorer or Firefox) on the local hard drive, and it can later be retrieved by the website.
Cookies were invented in 1994 so that information could be saved between visits to a website. This lets you avoid logging in for every visit, and cookies are also used to keep track of preferences and works in progress (such as items in an online shopping cart). Today, just about all of the top websites use cookies for one purpose or another. Cookies are a very useful feature of the web and, without them, web sessions would have no history; you would have to enter your information over and over.
Third-Party Cookies
Initially, cookies were only shared between the website (the “first party” in the transaction) and the user (the “second party”). Soon after cookies were invented, however, their use was expanded to third parties—organizations not directly involved in the interaction—such as advertising companies displaying ads on certain websites.

When an advertisement is on a web page supplied by a first party, the advertising content and a cookie are passed from the advertising company (the third party) to the end user’s (your) computer. Later, when you revisit that same first-party website, or another site that uses the same advertising company, the third-party cookie can be retrieved by the advertising company. If the cookie contains a unique identifier, then information about your visits to different websites can be linked together.
Further, if any of the sites (such as social networking sites) collect personal information, this information might also be collected by the advertisers. In this way, advertising companies are able to track the websites that you visit and build up detailed personal profiles, which may then be used to target further advertising to you.
Third-party cookies raise privacy concerns because the transactions typically involve unknown third parties and are conducted without your knowledge or consent. Unless you pay attention to an often-confusing set of options in your browser software, the cookies are created and used invisibly, and the information that is gathered may be stored forever. In addition, the tracking and profiling done by advertising companies can be extensive; it is common for your computer to collect dozens of third-party tracking cookies.

Flash cookies (also called Local Shared Objects or LSOs) are created by Adobe’s popular Flash browser add-on for multimedia. Like traditional cookies, Flash cookies can be used to save state information, as well as preferences, between sessions. They are also used to track the websites that you visit. These cookies are normally not visible to you, the end user, and options to control or delete them are usually absent or very difficult to find. Flash cookies are frequently found on websites, and they are often used along with traditional web cookies. In fact, even if you delete web cookies, Flash cookies can be used to recreate them.
Flash cookies raise additional privacy concerns because they are more hidden than traditional web cookies, so you have to take extraordinary measures to remove them. Also, many privacy policies that describe the use of web cookies fail to mention Flash cookies, and procedures to opt out of web cookies often have no effect on Flash cookies.
Super Cookies
A third type of cookie, called “super cookies,” is also emerging. Super cookies use new storage locations built into browsers to save information about you. For example, the Internet Explorer browser has “userData” storage, while Firefox has “DOM” storage”. The emerging HTML 5 specifications also set aside web storage that can last either for a browser session or permanently (until deleted). These storage mechanisms are larger and more flexible than traditional cookies so more information can be stored. Like web cookies and Flash cookies, you, as a user, are often unaware that super cookies exist. You, as the user, are often not provided with tools to control the information that is stored.
Cookie-Less Tracking
A person’s browsing habits can also be tracked without cookies. One such method involves “web bugs”, which are small, invisible image files placed on a web page or hidden in an e-mail message. When you view the page or message, the image is downloaded from a server that can keep detailed logs. These logs record such information as your location, Internet address, the page or message you are reading, and the current date and time.
When people view web pages, their browsers can reveal a lot of information. The browsers can be queried to determine their detailed characteristics, including version number, window size, settings, add-ons, and customizations. The combination of information, often called “device fingerprinting,” can be quite specific to an individual machine. An experiment conducted by the Electronic Frontier Foundation suggests that this information may be unique to about one in one million people.
Web Privacy Tools
Unfortunately, protecting privacy while browsing the web is not an easy task. Web browsers provide some tools for storing and clearing cookies. However, the default is to store all cookies indefinitely and the privacy tools are often hard to find and use. Browsers can be set to block cookies, but many websites require that you, as a user, allow cookies to use the service. Even blocking third-party cookies can impair the experience of some services, so users are faced with the onerous task of allowing some cookies and not others. If you do configure your browser to delete stored cookies, this often only clears traditional cookies, without removing super cookies and Flash cookies.
Some browsers have recently implemented a “private browsing mode,” designed to protect privacy. In Firefox, for example, web cookies are deleted when a private browsing session is ended. Unfortunately, super cookies and Flash cookies are not always affected by these settings, so they are still stored during private browsing sessions. In order to clear all the different forms of cookies and web storage, you generally have to install and use special add-on applications. Some popular tools for Firefox, for example, are the BetterPrivacy, NoScript, and Targeted Advertising Cookie Opt-Out (TACO) plug-ins.
Conclusion
Cookies are powerful tools that give the web a memory, making for a better user experience. They do, however, also pose privacy concerns because they are often used without your knowledge or consent, and can be used to track your web habits and build detailed personal profiles about you.
To protect your privacy on the web, you need to learn about the cookie controls provided in your browser. You should also investigate some specialized tools that can control all cookie types. Unfortunately, however, even if you do make the effort to control cookies, there is little that you can currently do to protect against cookie-less tracking methods.
The OPC is studying this issue. We raised concerns about tracking practices in our Report on the 2010 Consultations on Online Tracking, Targeting, and Profiling, and Cloud Computing. We will continue to address our concerns with industry, as appropriate.

What's a cookie?
If you've been anywhere on the internet, you've probably heard of cookies (also known as computer cookies or HTTP cookies). These are small files that websites want to put on your computer and store in your web browser.
But should you accept or block cookies?
Cookies don't infect your computer with malicious software or viruses. They're basically just text files to be read by whatever website or third party put them there. They have a range of uses, some you may like more than others.
The good news is it's not an all-or-nothing affair. Most browsers let you control which kinds of cookies are allowed. Here's how to manage them in Google Chrome, Apple's Safari, and Microsoft Edge – the Windows 10 default browser that replaced Internet Explorer.

Cookie 5 5 4 – Protect Your Online Privacy Screen
First-party cookies
First-party cookies belong to the website you're currently on and don't track what you do on other websites.
There are two kinds of first-party cookies:
Session cookies
Paws for trello 1 1 0 download free. These are short-lived and are usually deleted when your browser closes.
Without these cookies, every time you clicked a link – even to load a new page on the same website – it would forget you'd ever been there. For example, say you're shopping online and you add an item to your cart. If you then view another item on a different page, once the new page loads your cart would be empty because there'd be no way to track what you did previously.
Or perhaps a website asked you what language you'd prefer. Without session cookies, you'd have to re-select it with each new page.
Persistent cookies
These live on in your browser after it closes, but self-destruct after a predetermined time – usually within six months. If you ever asked a website to remember your login details, it did so with a first-party persistent cookie.
Persistent cookies may also be used to remember what you read or did while you were on the site, to avoid showing you the same content if you log back on later. While some persistent cookies are first-party, not all are.
Third-party cookies
These are also persistent. They're often used for tracking your movements to gain marketing or demographic data.
If you disable third-party cookies it'll make it harder for advertisers to get information about your online activity. You'll still see ads; they just probably won't be tailored to your interests.
Third-party cookies have also been blamed for slowing down web page loading times. Some browsers, such as Safari and Firefox, block them by default. Others let you opt-out in their settings menu.
How to manage cookies in Google Chrome
At the top-right of a browser window, click the menu button (three vertical dots), then Settings. Scroll down and click Advanced.
In the Privacy and Security section, click Content Settings then Cookies. Turning cookies off completely would disable all the features we've talked about so far, not just the tracking ones. So it's advisable to not block them entirely.
If you enable Keep local data online until you quit your browser, you'll still be able to add items to a shopping cart, but every time you close your browser you'll lose things like automatic sign-ins on your favourite websites.
Block third-party cookies stops the marketing-led cookies that track your internet usage and patterns, while leaving the more-useful cookies running.
If you'd like a fresh start with your new cookie settings, you can delete all your current ones. Click See all cookies and site data, then Remove All.
How to manage cookies in Safari (on macOS)
Since a Safari update in 2017, third-party cookies are blocked by default.
To manage your cookie settings, open Safari and click the Safari menu at the top-left (next to the Apple menu) and select Preferences. In the following window, select Privacy.
Prevent cross-site tracking should be enabled by default. This stops third-party cookies that track you across websites for advertisers.
Ask websites not to track me requests websites to not use both third-party and first-party persistent cookies. It's up to the website to respect your request.
Block all cookies will stop third-party cookies, but also the first-party cookie features mentioned earlier.
To delete the cookies you already have, click Manage Website Data and select cookies from individual websites on the list and click Remove, or select Remove all to delete the lot.
How to manage cookies in Microsoft Edge
Click the ellipsis (…) icon at the top right and select Settings. Scroll down and under Advanced settings, select View advanced settings. Scroll down again and under Cookies there are three options: Block all cookies, Block only third party cookies and Don't block cookies.
If you want to stop other parties tracking your online activity, select Block only third party cookies. This should make it harder for targeted advertisers and data analytics firms to get information about you.
If you Block all cookies then none of the functions we mentioned earlier will work (auto login, adding items to a shopping cart, etc.) and some websites may become unusable.
To delete the cookies you already have, go to Settings then under Clear browsing data, click Choose what to clear. Make sure Cookies and saved website data is ticked, then hit Clear.
