Part 1. What Is Html5 Offline Storage Space?

HTML5 Local Storage is actually a part of the Web storage application programming interface. It’s one way of the web page to locally create a storage of data within a user’s web browser. It is similar to cookies in a certain way--the stored data still exists even after a browser tab is closed, even when you surf from one website to another, even when you close a tab, and even when the main browser is quit.

However, it is different from cookies in that the data is not sent to a remote Web server unless it is done manually. HTML5 local storage is integrated into various web browsers and is available without the need for third-party browser extensions or plug-ins.

The local storage is used for the storage and retrieval of data in HTML pages from the same domain. Even if a browser is restarted, recovery of data from all windows in the same domain can be done. With HTML5 Offline Local Storage, a larger amount of data can be stored compared to cookies. The data is also referred to as more secure.

So, what’s the problem with it? Well, data is stored in your computer (in this case, your Mac) and when it accumulates over time, it takes up so much space. Therefore, clear HTML5 offline storage is as important as clear cookie on Mac.

So, we are here to show you some easy ways you can do to clear local storage from browsers like Chrome and Firefox. Moving on to next part!
