Firefox Tackles Persistent Supercookies in Latest Update - Drops Progressive Web App Support
Firefox has dropped support for progressive apps due to supercookies. Learn how this affects your browsing experience and privacy.
Firefox, one of the most popular web browsers, has recently rolled out an update that aims to tackle a new form of tracking called supercookies. These persistent cookies can track users across websites and devices, even if they have cleared their browser data. While this move has been praised by privacy advocates, Firefox also made an unexpected decision to drop support for progressive web apps (PWAs). This marks a significant shift in the browser's strategy and has left many developers wondering about the future of web applications.
Supercookies, also known as evercookies or zombie cookies, are a more advanced form of tracking than traditional cookies. They are designed to persistently store user data, making it nearly impossible for users to opt-out or delete them. This has raised concerns about online privacy and security, as supercookies can be used to target users with personalized ads or even to identify them across different devices.
Firefox's solution to this problem is a new feature called Total Cookie Protection. This isolates cookies on a per-website basis, preventing them from being shared across sites. This means that even if a website tries to use a supercookie, it will only be able to track users within that site. While this may not completely eliminate the problem, it does make it much harder for advertisers and trackers to follow users across the web.
However, while Total Cookie Protection is undoubtedly a step forward for online privacy, it comes at a cost. Firefox has decided to drop support for PWAs, which are a type of web app that can be installed on a user's device and behave like native apps. This decision has been met with mixed reactions, as PWAs were seen as a promising alternative to native apps, especially for smaller businesses and independent developers.
The reason behind this move is that PWAs rely on caching techniques that are similar to those used by supercookies. While PWAs do not track users in the same way, they do use caching to store data offline and improve performance. This means that if a user visits a PWA, it could potentially access data from other PWAs on their device, which raises privacy concerns. By dropping support for PWAs, Firefox is sending a clear message that online privacy is its top priority, even if it means sacrificing other features.
So what does this mean for developers and users? For developers, this means that they will have to find alternative ways to create web apps that do not rely on PWAs. This could involve using traditional web technologies like HTML, CSS, and JavaScript, or exploring newer technologies like WebAssembly and Web Components. While this may be a setback for some developers, it also presents an opportunity to innovate and create new solutions.
For users, the impact of this decision is less clear. While Total Cookie Protection is a welcome addition to Firefox's privacy arsenal, dropping support for PWAs could limit the availability and functionality of web apps. However, it is worth noting that Firefox is not the only browser to take this approach. Apple's Safari browser has also limited support for PWAs, citing similar privacy concerns.
Overall, Firefox's decision to tackle supercookies and drop support for PWAs marks a significant shift in the browser's strategy. It shows that online privacy is becoming an increasingly important issue for both users and developers, and that browsers are willing to make tough choices to protect it. While there may be some short-term challenges for developers and users, this move could ultimately lead to a more secure and privacy-focused web.
Introduction
Firefox is a web browser that has been around since 2002. It is a popular browser known for its privacy features. However, recently, Firefox came under fire for using supercookies and dropped Progressive Web Applications (PWA). In this article, we will discuss what supercookies are, how they work, and why Firefox dropped PWA.
What are supercookies?
Supercookies are not your regular cookies. They are designed to store data in places where regular cookies cannot. Supercookies can be used to track your online activity, even if you clear your cookies regularly. These cookies use various storage methods, such as Flash storage, HTML5 storage, and ETags, to store data on your computer.
How do supercookies work?
Supercookies work by creating unique identifiers that are stored on your computer. These identifiers are then used to track your online activity. Unlike regular cookies, supercookies are difficult to detect and remove. They can also recreate themselves if deleted.
Why are supercookies a concern?
Supercookies are a concern because they can be used to track your online activity without your consent. They can be used by advertisers to serve you targeted ads and by websites to monitor your behavior. Supercookies can also be used to collect personal information, such as your name and address.
Firefox's use of supercookies
In 2014, Firefox was found to be using supercookies to track its users. Mozilla, the company behind Firefox, claimed that it was using the cookies to improve its website. However, users were not happy about this and demanded that Firefox stop using supercookies.
Firefox drops supercookies
In response to the backlash, Mozilla announced that it would stop using supercookies in Firefox. The company also released an update that allowed users to delete all supercookies from their browsers. This move was welcomed by privacy advocates and users alike.
What are Progressive Web Applications?
Progressive Web Applications (PWA) are web applications that use modern web technologies to provide an app-like experience to users. PWAs are designed to work on any device and platform. They can be installed on your device and work offline.
Why did Firefox drop PWA?
In 2021, Firefox announced that it was dropping support for PWA. The company claimed that it was doing so because PWAs are not widely used. Firefox argued that the technology was not mature enough and that users were not interested in using PWAs.
The backlash against Firefox's decision
Firefox's decision to drop PWA was met with backlash from the developer community. Developers argued that PWAs are essential for the future of the web. They claimed that PWAs provide a better user experience and that they are more accessible than native apps.
Firefox's response to the backlash
In response to the backlash, Firefox clarified that it was not dropping support for PWAs entirely. The company claimed that it was only dropping support for PWA as a standalone product. Firefox stated that it would continue to support PWAs that are built into websites.
Conclusion
Firefox's use of supercookies and its decision to drop support for PWA have been controversial. While the company has addressed the concerns over supercookies, its decision to drop PWA has been met with criticism. Despite this, Firefox remains a popular browser known for its privacy features.
Firefox Supercookies and Dropped Progressive App: What You Need to Know
In today's digital age, privacy has become a major concern for internet users. Many websites use cookies to track user behavior and personalize their online experiences. However, there is a new type of cookie that is more advanced and harder to detect - Firefox Supercookies. In this article, we will explore what Firefox Supercookies are, how they differ from regular cookies, why they are harmful to privacy, and what can be done to protect yourself.What are Firefox Supercookies?
Firefox Supercookies, also known as Evercookies, are a more advanced type of cookie that can store data on users' devices for extended periods of time, even when users clear their browser history or delete their cookies. Supercookies are not stored in the usual places where cookies are stored but are rather embedded in various locations throughout the browser, such as the cache, HTML5 storage, and Flash cookies. This makes it difficult for users to detect and delete these cookies.How do Supercookies differ from regular cookies?
Unlike regular cookies, which expire after a set period or are deleted when users clear their browsing data, Supercookies can remain on users' devices indefinitely, as they are stored in multiple locations across the browser. They are also much harder to detect and delete, as they can be recreated from other sources if one source is deleted. Supercookies can also be used to track users across different websites and devices, allowing advertisers to build detailed profiles of users' online behavior.Why are Supercookies harmful to privacy?
Supercookies are harmful to privacy because they can track users' online behavior without their knowledge or consent. They can be used to collect personal information, including browsing history, search queries, and login credentials. This information can then be used to target users with personalized advertising and even sold to third-party companies. Supercookies can also be used to bypass privacy settings, such as ad-blocking software, and collect data on users who have opted out of tracking.How do Supercookies track user behavior?
Supercookies track user behavior by collecting data from multiple sources across the browser, including the cache, HTML5 storage, and Flash cookies. They can also collect data from browser plugins and extensions. Supercookies can then use this data to build a detailed profile of users' online behavior, including their browsing history, search queries, and login credentials. This information can be used for targeted advertising and other purposes.What is Mozilla doing to combat Supercookies?
Mozilla, the organization behind the Firefox browser, has taken several steps to combat Supercookies. In 2011, Mozilla introduced a feature in Firefox that allowed users to block third-party cookies by default. In 2019, Mozilla announced that it would start blocking Supercookies by default in Firefox. This means that websites will no longer be able to use Supercookies to track users across different websites and devices. Mozilla has also been working on developing new privacy features, such as its Enhanced Tracking Protection, which blocks trackers and other unwanted content.How can users protect themselves from Supercookies?
Users can protect themselves from Supercookies by taking several steps. First, they can use a browser that blocks Supercookies by default, such as Firefox. Second, they can regularly clear their browser history and cookies. Third, they can use privacy-focused browser extensions, such as uBlock Origin or Privacy Badger, which can block Supercookies and other online trackers. Fourth, they can use a virtual private network (VPN) or Tor browser to hide their online activity from prying eyes. Finally, they can be cautious about the information they share online and avoid clicking on suspicious links or downloading unknown files.Are Supercookies legal?
Supercookies are legal, but their use is subject to regulations and guidelines set by government agencies and industry groups. In the United States, the Federal Trade Commission (FTC) has issued guidelines on online tracking and privacy that require websites to obtain users' consent before collecting their personal information. In the European Union, the General Data Protection Regulation (GDPR) requires websites to obtain users' explicit consent before collecting their personal data. However, some websites may use Supercookies without users' knowledge or consent, which can be a violation of these regulations.What are the implications of Supercookies for online advertising?
Supercookies have significant implications for online advertising. They allow advertisers to build detailed profiles of users' online behavior, which can be used to target ads more effectively. Supercookies can also be used to bypass privacy settings, such as ad-blocking software, and collect data on users who have opted out of tracking. However, the use of Supercookies has also raised concerns about privacy violations and the potential for abuse by third-party companies.How are other browsers dealing with Supercookies?
Other browsers have also taken steps to combat Supercookies. Apple's Safari browser has been blocking third-party cookies by default since 2017. Google's Chrome browser has announced plans to phase out support for third-party cookies by 2022. Microsoft's Edge browser has introduced a feature called Tracking Prevention, which blocks trackers and other unwanted content. However, some critics argue that these measures do not go far enough and that more needs to be done to protect users' privacy.What is the future of Supercookies and online privacy?
The future of Supercookies and online privacy is uncertain. While browsers and regulators are taking steps to combat Supercookies, new technologies are emerging that may make it even harder to protect users' privacy. For example, fingerprinting is a technique that can be used to track users even if they have cleared their cookies or are using privacy-enhancing tools. As technology continues to advance, it will be important to stay informed about the latest threats to online privacy and take steps to protect ourselves.Firefox Supercookies and Dropped Progressive App: A Point of View

Thank you for taking the time to read this article about Firefox's decision to drop supercookies, also known as progressive apps. We hope that this information has been informative and helpful in understanding the implications of these types of cookies on your online privacy.
For those who may not be familiar with supercookies, they are a type of tracking mechanism that allows websites to store data on a user's device, even after they have cleared their browser history or cookies. This means that advertisers and other third-party entities can continue to track your online activity, even if you have taken steps to protect your privacy.
Firefox's decision to drop support for supercookies is a significant step towards protecting users' online privacy. By doing so, Firefox is taking a stand against invasive tracking practices that threaten our online security and personal information. This move by Mozilla is just one example of how tech companies are beginning to prioritize user privacy over profits.
However, it's important to note that dropping supercookies does not mean that Firefox is abandoning all forms of tracking. Like other browsers, Firefox still allows websites to use first-party cookies, which are necessary for certain features to work properly. These cookies are designed to remember your login information, preferences, and other settings that make your browsing experience more personalized and efficient.
Despite this, it's clear that Firefox is committed to providing users with greater control over their online privacy. For example, the browser includes several features that help users block unwanted tracking, such as the ability to disable third-party cookies, block trackers, and enable private browsing mode.
Firefox's stance on supercookies is particularly noteworthy given the recent controversy surrounding Google's decision to phase out third-party cookies on its Chrome browser. While this move has been praised by some privacy advocates, others have criticized Google's approach as being too focused on its own business interests rather than the needs of users.
Ultimately, the decision to drop support for supercookies is a positive development for online privacy. By taking steps to limit invasive tracking practices, Firefox and other tech companies are helping to ensure that users' personal information is protected while they browse the web.
Of course, there are still many challenges to be faced in the ongoing battle for online privacy. Advertisers and other third-party entities will continue to find new ways to track users' activity, and it's up to tech companies and policymakers to stay vigilant and ensure that users' rights are protected.
In conclusion, we encourage you to continue following developments in the world of online privacy and take steps to protect your personal information while browsing the web. Whether you use Firefox or another browser, it's important to stay informed about the latest trends and technologies that can help keep you safe online.
Thank you again for reading this article, and we hope that you found it useful and informative. Remember to stay safe, stay informed, and above all, stay vigilant when it comes to protecting your online privacy.
