How to clean and clear the cache of Internet Explorer, Firefox, Opera, Safari, Edge and Chrome browsers on PC and Android and iPhone smartphones

Empty browser cache
Regular readers of know very well how to clear the cache of their web browser, but they don’t often do it because they know that the cache is useful for loading websites faster. Less experienced people, on the other hand, may know nothing about what “cache” means, let alone know how to delete temporary files stored after an internet browsing session, or they know it by doing it too often.The cache, when referred to web browsers, is a temporary memory of the computer where the files of the open websites are saved which, to show things like logos and images, download some data into the memory of the computer. The aim is to speed up the loading time of the same site when you visit it again. Graphic elements of the sites, such as the logo on the top left, can therefore be loaded from the cache saved on the computer disk and not downloaded from the internet (from the web server) again.
Among the temporary browser files are stored also cookies, small files that can be injected into your computer when you visit a website. We have explained what internet cookies are and explained who creates cookies and how they can be blocked or deleted in other dedicated articles.

Each browser saves the cache in a different location on the computer disk, usually a fairly hidden internal folder. Emptying the cache meansthen delete the contents of this folder and delete all the files. We use to clean the cache of the web browser, therefore, to remove traces of the sites visited and even when you want recover disk space if it is very limited, however recover memory on your smartphone. Clearing the cache is one of those operations that allows you to solve any problems in viewing a website, in order to re-download the data from scratch without using the data saved in the cache that may be wrong or old.
Summarizing the meaning of cache, cookies and history we see that:
Clear your browser cache it is used to delete stored files of the sites visited and often allows to resolve any loading errors.
Delete the cookies instead it allows to remove from the computer the traces of internet use, the saved logins and passwords and the data of each session.
Clear history instead it is a matter of privacy, to prevent others from seeing which sites have been visited by that computer.
