How To Clear Cache & Cookies in Different Browsers

As you use the web, browsers collect data about your preferences, searches, and internet history. To keep your browser running optimally, it's a good idea to clear your cache and cookies periodically. Read on to find out how you can delete history across multiple browsers.

What is a cache?

The term ‘cache’ refers to the portion of your hard drive dedicated to storing browser files that your browser thinks it may use again. Without this feature, your browser would operate more slowly since every website you opened would need to download a large number of files from scratch each time.

This includes elements like the website logo, background images, fonts, plus technical aspects such as CSS, HTML, and JavaScript. Cumulatively, these can add up to dozens, hundreds, or even thousands of files for just one website. The cache stores these files locally, so future website visits are quicker, improving your overall internet experience.

So, why clear cache?

Clearing your cache means deleting all the saved information from your local hard drive that has been stored in the cache. Some of the reasons why you may want to clear browsing history include:

Maximizing performance:

Depending on your settings, your cache can grow quite large and take up significant disk space on your computer. The more information saved in the cache, the slower your computer will be when browsing online. Deleting your cache can help increase website loading times and improve the performance of your device.

Viewing most recent pages:

In theory, whenever you revisit a website, your cache checks to see if it has changed so it can show you the most up-to-date pages. However, this doesn’t always happen: sometimes the cache will load its older stored pages instead, which means you may not see the newest version. By periodically clearing your cache, you force your browser to start afresh, ensuring that you view the latest pages and information.

Maintaining security:

If you are using a public or shared computer, clearing your cache may help protect your privacy. If you don't clear your cache, then anyone who uses the computer after you may be able to see your browser history. The cache can also store private data required by some websites, which could give the next user on the computer access to sensitive or personal information. The cache's temporary files may also be a target for adware, malware, and viruses.

Fixing browser errors:

Your cache can sometimes cause browser issues. For example, you may find that certain websites are slow to load or only partially load, will not open, return an error message, or otherwise don’t respond as they should. Often, you can fix these types of errors by clearing your cache before closing and reopening your browser.

Why clear cookies?

Cookies are simple text files that a website can store on your browser. They are designed to identify users, save site login details or create customized web pages tailored to the individual’s preferences. You can read more about cookies here.

People sometimes review cookie settings or cookie preferences or delete cookies on their browser. This is to:

Enhance security – Hackers can potentially hijack cookies, giving them access to browser sessions and enabling them to steal personal data.
Protect personal information – Cookies collect personal information about you. Websites use this information to track your internet activity to develop a more detailed profile of your online habits or target you with tailored ads.
Exercise caution when using public or shared computers. When using a public computer, unless you delete your cookies after every session, the next person who logs on could potentially see your browsing history. They could even log in to your online banking or shopping accounts if you forget to log out.
Speed things up – When you first visit a website, the pages you visit are saved onto your hard drive. On subsequent visits, instead of re-downloading the pages, it will load more quickly. However, over time you may accumulate numerous cookies, which will slow your system down. Deleting them can help to speed things up.

What is the difference between cache and cookies?

Both cache and cookies are designed to improve website performance and user experience through storing data on your devices. However, there are differences between the two:

Cookies are used to store information to track different characteristics related to the user, while the cache is used to make web pages load faster.
Cookies store information such as user preferences, while cache retains resource files such as audio, video, or flash files.
Cookies usually expire after some time, but cache remains in the user’s device until manually removed.

A VPN can help to ensure your privacy online without so many steps

Some people don’t like clearing their cookies because they appreciate the convenience of not having to log in constantly to their favorite websites. For those users who still want to maximize their online privacy, a Virtual Private Network or VPN could be an excellent option to consider. A VPN like Kaspersky Security Connection encrypts data being transmitted to and from your computer, blocks ad trackers from intercepting cookies, and removes your personally identifiable information.
