About cache, cookies, and history

Whenever you access a new website in your web browser, the browser stores the files (such as HTML files, images, and cookies) associated with the webpage. It does this so that it does not need to retrieve the files again if you click Back or Forward. Over time, these files build up, taking up storage and processing resources, making your browser slow down.

Among these files are cookies, which are created by your web browser, at the request of a website, to store information specific to your visit to the website. This information can include form contents, log in information, or the contents of your shopping cart. While your browser automatically clears cookies when they reach a certain age, some can cause access problems when you visit a website again. Manually removing these cookies may solve these access problems.

Your browser also stores a log of the sites that you visit, allowing it to know where to move when you hit the Back or Forward buttons. Like cookies, your history is cleared regularly by your browser, but it can easily be cleared manually to preserve privacy
