Why You Should Clear Your Android Browser’s Cache and Cookies



The web browsers of your Android devices, whether it's Google Chrome, Mozilla Firefox, or Samsung Internet, stores a variety of files, images, and data from the websites you visit. While this data can help load sites faster and keep you logged in, it also accumulates a lot of unnecessary information. This data buildup can potentially pose privacy risks.

Over time, your browser’s cookies and cache collect a lot of junk files. Some of this data comes from sites you’ve visited only once, while others track your browsing habits to serve targeted ads. For example, you might see frequent ads for items you viewed recently. Clearing your cache regularly helps eliminate this unnecessary data, reducing the risk of unknown data trackers lurking in your browser.

Though clearing your cache means you’ll have to log back into your favourite websites, it’s a small inconvenience compared to the benefit of protecting your privacy and freeing up storage space on your phone.

How to Clear Cookies and Cache in Google Chrome

To clear cookies and cache in Google Chrome on your Android device, tap the More button (three vertical dots) in the top right corner. Go to History and then Delete browsing data. Alternatively, you can navigate through Chrome’s Settings menu to Privacy and Security, and then Delete browsing data. You’ll have options under Basic and Advanced settings to clear browsing history, cookies and site data, and cached images and files. You can choose a time range to delete this data, ranging from the past 24 hours to all time. After selecting what you want to delete, tap Clear data.

How to Get Rid Of Unnecessary Web Files in Samsung Internet

For Samsung Internet, there are two ways to clear your cookies and cache. In the browser app, tap the Options button (three horizontal lines) in the bottom right corner, then go to Settings, and select Personal browsing data. Tap Delete browsing data to choose what you want to delete, such as browsing history, cookies, and cached images. Confirm your choices and delete.

Alternatively, you can clear data from the Settings app on your phone. Go to Settings, then Apps, and select Samsung Internet. Tap Storage, where you’ll find options to Clear cache and Clear storage. Clear cache will delete cached files immediately, while Clear storage will remove all app data, including cookies, settings, and accounts.

How to Declutter in Mozilla Firefox

In Mozilla Firefox, clearing cookies and cache is also straightforward. Tap the More button (three vertical dots) on the right of the address bar, then go to Settings and scroll down to Delete browsing data. Firefox offers options to delete open tabs, browsing history, site permissions, downloads, cookies, and cached images. Unlike Chrome, Firefox does not allow you to select a time range, but you can be specific about the types of data you want to remove.

Firefox also has a feature to automatically delete browsing data every time you quit the app. Enable this by going to Settings and selecting Delete browsing data on quit. This helps keep your browser tidy and ensures your browsing history isn’t accessible if your phone is lost or stolen.

Regularly clearing cookies and cache from your Android browser is crucial for maintaining privacy and keeping your device free from unnecessary data. Each browser—Google Chrome, Samsung Internet, and Mozilla Firefox—offers simple steps to manage and delete this data, boosting both security and performance. By following these steps, you can ensure a safer and more efficient browsing experience on your Android device.


Is Wave Browser Safe ?


Unless it is an ultimate exception, everyone has a browser installed on their computer and smartphones to surf the web, work, communicate with others and more. 

However, there are significant differences in browsers. Some browsers prioritize speed and convenience, some privacy, while other browsers focus on certain specialized tasks. And there come browsers that are potentially wicked, such as the Wave browser. 

Is Wave Browser Safe? 

On their official websites, Wave browsers portray themselves as an alternative to mainstream software that guarantees "anonymity of your data," and offers a personalized experience to users. "Not only do we not pass your data onto third parties, we don't even store it ourselves," the website states. 

Wave browser is available on Windows, MacOS, Android, and iOS. It can be installed via Google Play and App Store, indicating its successful marketplace requirement regarding functionality and security.

The Wave browser is classified as a Potentially Unwanted Program (PUP). PUPs, as the term suggests are not very harmful. However, certain behaviours displayed by PUP do cause indirect or direct harm: display unwanted ads, slow down the user's device, collect an excessive amount of data, etc. 

Wave browsers are almost every time installed unintentionally, attached to other software. For instance, a user’s antivirus software may fail to detect Wave, consequently making him download and install the malicious browser. During its installation, the browser may even trick the user into clicking certain boxes, which ultimately enables it to import data and become their default browser. 

A user may not even recognize anything suspicious, since Wave is, in fact, a browser. Wave browser is based on Chromium, the open-source web browser project that is the foundation for Chrome, Microsoft Edge, Brave, and several other similar products. However, after a few minutes of its installation, the user will realize what has transpired, since their system will be bombarded with annoying ads and pop-ups. Also, a user may take a hint when their browser becomes incapable of showing relevant search results and only displays search ads, or links leading to websites unrelated to the keyword they may have entered.

Since Wave will not display any relevant search results, but instead they may lead the users into paying for advertising, one may encounter shady webpages, that may as well contain a malware. While Wave itself is not a malware, it may lead its victim to phishing sites or malicious programs, entailing risk to their privacy and security. 

This answers the question of ‘Is Wave browser safe?’ which is ‘No, it is not.’ While it is neither a virus nor any malware, it certainly should not be there in a user’s device. Wave browser will only serve them with annoying ads, display irrelevant search results and compromise their security, at worst.  

Security Experts Unearthed the Flaws in EPUB Similar to Web Browsers

 

Security researchers at imec-DistriNet Research Group have discovered the vulnerabilities in e-book reading systems that allow hackers to exploit the user’s system by targeting the specific aspects of the electronic publication (EPUB). 

Security researchers Gertjan Franken, Tom Van Goethem, and Wouter Joosen published a research paper that reads that e-book reading systems have similar flaws to web browsers. The electronic publication (EPUB) format depends primarily on XHTML and CSS (Cascading Style Sheets) to design e-books, with browser engines often used to render their contents.

Unfortunately, none of the e-book reading systems researchers properly followed the EPUB specification’s security guidelines. The researchers used the semi-automated testbed to identify that 16 of the 97 systems allowed an EPUB to leak information about the user’s file system, and in eight cases, extract file contents. Researchers warned that hackers could easily achieve full e-book reading systems.
 
"Of course, the significance depends on the platform that is used; e-readers generally won't contain sensitive files, while smartphones could contain private pictures," Franken told The Daily Swig. The team also carried out a manual evaluation of the most popular EPUB reading applications on Amazon Kindle, Apple Books, and the EPUBReader browser extension - and found several flaws.

"For instance, the Amazon Kindle does not allow an EPUB to execute embedded JavaScript. Nevertheless, this can be circumvented by a creative attacker through an input validation issue. The embedded scripts could then exploit a publicly known vulnerability of the Kindle's outdated web engine to gain access to documents in the user's library. The embedded scripts could then exploit a publicly known vulnerability of the Kindle's outdated web engine to gain access to documents in the user's library," Franken explained.

Vulnerabilities were also discovered in Apple Books, available pre-installed on macOS, and in the Windows version of Adobe Digital Editions. 

"Fortunately, the developers of Amazon, Apple, and Adobe were very responsive to our bug reports and were eager to fix the issues. Secondly, we argue that practical guidelines on how to handle the security and privacy aspects of developing a EPUB reading application would greatly aid developers. Ideally, this would include guidelines on how to correctly configure popular browser engines, such that important security policies prevent an EPUB from gaining too much [many] privileges,” Franken concluded.
