Web browsers store temporary data such as images, scripts, and other files on your computer or device in a location called the cache. This allows web pages to load faster when you visit them again in the future, because the browser can access these stored files instead of downloading them all over again. Sometimes, web pages may not load properly due to corrupted or outdated files in the cache. Clearing the cache can fix these issues and allow the browser to download fresh files from the website.
Note: While clearing your cache can improve performance and fix some browsing issues, it is likely to log you out of websites (all you need is to re-login again).
