Functionality
Once installed and enabled, Lightbeam records all tracking cookies saved on the user's computer through the Firefox browser by the various sites that the user visits. [3] It differentiates between "behavioural" tracking cookies (those which record specific actions on a site) and other tracking cookies. [4] [5] At any time during a browsing session the user can open a separate tab, using the "Show Lightbeam" option of Tools, to display a graph of sites visited and cookies placed. This will show when a given cookie is used by multiple sites, thus enabling those sites to track the user from site to site. Lightbeam will also allow the user to see which advertisers or other third parties are connected to which cookies, and thus can develop information about the user's browsing from site to site. [4] [5]
Mozilla emphasizes that it displays its data in real time. [3] [5]
According to Mozilla, all data collected by Lightbeam is stored locally, and is not shared with anyone, unless the user intentionally exports the data and shares it manually. [4] [5] Future versions may include provisions to reject or delete tracking cookies as well as monitoring them. [4]
Reactions
Writing for ExtremeTech , Sebastian Anthony found the tracking connections revealed by Collusion to be "quite astonishing". [8] He went on to say that: "Now, you can either use Collusion to shock and appall yourself, or you can use it to show friends and family just how rampant behavioral tracking is. Once your mother sees that no less than five companies track her behavior when she visits MSNBC.com, and six when she visits FoxNews.com, she might be a little more cautious." [8]
"Ms Smith" finds the results of Collusion to be "jaw dropping". [5]
Stephen C. Webster, writing for The Raw Story wrote of the information provided by Collusion: "While it doesn’t sound all that creepy, just wait until you see your own graph. A brief test-run by Raw Story revealed that after clicking a number of popular websites — like Comedy Central, Netflix, Hulu, the Conan O’Brien show, Amazon, The New York Times and others — more than three dozen organizations were tracking our movements across multiple websites."

A web browser is an application for accessing websites. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers are used on a range of devices, including desktops, laptops, tablets, and smartphones. By 2020, an estimated 4.9 billion people had used a browser. The most-used browser is Google Chrome, with a 67% global market share on all devices, followed by Safari with 18%.
Mozilla Firefox, or simply Firefox, is a free and open source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. It uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards. Firefox is available for Windows 10 and later versions of Windows, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems, including FreeBSD, OpenBSD, NetBSD, and other platforms. It is also available for Android and iOS. However, as with all other iOS web browsers, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements. An optimized version is also available on the Amazon Fire TV as one of the two main browsers available with Amazon's Silk Browser.
A favicon, also known as a shortcut icon, website icon, tab icon, URL icon, or bookmark icon, is a file containing one or more small icons associated with a particular website or web page. A web designer can create such an icon and upload it to a website by several means, and graphical web browsers will then make use of it. Browsers that provide favicon support typically display a page's favicon in the browser's address bar and next to the page's name in a list of bookmarks. Browsers that support a tabbed document interface typically show a page's favicon next to the page's title on the tab, and site-specific browsers use the favicon as a desktop icon.
Internet privacy involves the right or mandate of personal privacy concerning the storage, re-purposing, provision to third parties, and display of information pertaining to oneself via the Internet. Internet privacy is a subset of data privacy. Privacy concerns have been articulated from the beginnings of large-scale computer sharing and especially relate to mass surveillance.

HTTP cookies are small blocks of data created by a web server while a user is browsing a website and placed on the user's computer or other device by the user's web browser. Cookies are placed on the device used to access a website, and more than one cookie may be placed on a user's device during a session.
A local shared object (LSO), commonly called a Flash cookie, is a piece of data that websites that use Adobe Flash may store on a user's computer. Local shared objects have been used by all versions of Flash Player since version 6.
Mozilla Firefox 4 is a version of the Firefox web browser, released on March 22, 2011. The first beta was made available on July 6, 2010; Release Candidate 2 was released on March 18, 2011. It was codenamed Tumucumaque, and was Firefox's last large release cycle. The Mozilla team planned smaller and quicker releases following other browser vendors. The primary goals for this version included improvements in performance, standards support, and user interface.
Private browsing is a feature in some web browsers that enhances user privacy. In this mode, the browser initiates a temporary session separate from its main session and user data. The browsing history is not recorded, and local data related to the session, like Cookies and Web cache, are deleted once the session ends. The primary purpose of these modes is to ensure that data and history from a specific browsing session do not remain on the device or get accessed by another user of the same device. In web development, it can be used to quickly test displaying pages as they appear to first-time visitors.
Clickjacking is a malicious technique of tricking a user into clicking on something different from what the user perceives, thus potentially revealing confidential information or allowing others to take control of their computer while clicking on seemingly innocuous objects, including web pages.
HTTP Strict Transport Security (HSTS) is a policy mechanism that helps to protect websites against man-in-the-middle attacks such as protocol downgrade attacks and cookie hijacking. It allows web servers to declare that web browsers should automatically interact with it using only HTTPS connections, which provide Transport Layer Security (TLS/SSL), unlike the insecure HTTP used alone. HSTS is an IETF standards track protocol and is specified in RFC 6797.
Web tracking is the practice by which operators of websites and third parties collect, store and share information about visitors' activities on the World Wide Web. Analysis of a user's behaviour may be used to provide content that enables the operator to infer their preferences and may be of interest to various parties, such as advertisers. Web tracking can be part of visitor management.
Web browsing history refers to the list of web pages a user has visited, as well as associated metadata such as page title and time of visit. It is usually stored locally by web browsers in order to provide the user with a history list to go back to previously visited pages. It can reflect the user's interests, needs, and browsing habits.
Do Not Track (DNT) is a formerly official HTTP header field, designed to allow internet users to opt out of tracking by websites—which includes the collection of data regarding a user's activity across multiple distinct contexts, and the retention, use, or sharing of data derived from that activity outside the context in which it occurred.
Firefox was created by Dave Hyatt and Blake Ross as an experimental branch of the Mozilla browser, first released as Firefox 1.0 on November 9, 2004. Starting with version 5.0, a rapid release cycle was put into effect, resulting in a new major version release every six weeks. This was gradually accelerated further in late 2019, so that new major releases occur on four-week cycles starting in 2020.
Browser security is the application of Internet security to web browsers in order to protect networked data and computer systems from breaches of privacy or malware. Security exploits of browsers often use JavaScript, sometimes with cross-site scripting (XSS) with a secondary payload using Adobe Flash. Security exploits can also take advantage of vulnerabilities that are commonly exploited in all browsers.

HTTPS Everywhere is a discontinued free and open-source browser extension for Google Chrome, Microsoft Edge, Mozilla Firefox, Opera, Brave, Vivaldi and Firefox for Android, which was developed collaboratively by The Tor Project and the Electronic Frontier Foundation (EFF). It automatically makes websites use a more secure HTTPS connection instead of HTTP, if they support it. The option "Encrypt All Sites Eligible" makes it possible to block and unblock all non-HTTPS browser connections with one click. Due to the widespread adoption of HTTPS on the World Wide Web, and the integration of HTTPS-only mode on major browsers, the extension was retired in January 2023.
Firefox Focus is a free and open-source privacy-focused mobile browser by Mozilla, based on Firefox. It is available for Android and iOS smartphones and tablets. Its predecessor, Focus by Firefox, was released in December 2015 as a tracker-blocking application which worked only in conjunction with the Safari mobile browser on iOS. It was developed into a minimalist web browser in 2016 but retained this background blocking functionality. The Android version of the browser was first released in June 2017 and was downloaded over one million times in the first month. As of January 2017, it was available in 27 languages. The version released for German-speaking countries has telemetry disabled and is named Firefox Klar to avoid ambiguity with the German news magazine FOCUS.
