When it comes to cookies, you can have too much of a good thing, particularly when we are talking about internet cookies. Websites often places cookies on the machines of their visitors. A cookie has data that pertains to the website that left it. The idea is that the website will load faster the next time it is visited by the computer with the cookie because the computer doesn’t have to download the entire website, it can just grab a bunch of information from the cookie. Cookies work wonderfully in theory and they can work wonderfully in practice but if a computer has too many cookies, it can get bogged down and make things slower instead of faster. To stop this from happening, it is a good idea to clear your cookies from time to time. Here is how to clear your cookies on a Mac running OSx and Firefox.
A Macintosh computer running OSx
Click on Firefox in the top left corner of the screen and go to Preferences.
Click on the Privacy tab and then click on the “remove individual cookies” button, a new box will pop up.
Click on the “Remove All Cookies” button.
This step may take a few minutes depending on how many cookies you have to delete. Once completed, this box should be empty. If you have a corrupted cookie, this process may crash Firefox, in which case you will need to remove cookies one by one.
Close the Cookies box and then the Preferences box by clicking on the red circle in the top left corner of each box.
Cookies should be deleted once every few months, or if you notice that your internet is running slowly. Deleting your cookies may also help if a particular site that you have visited before suddenly stops loading.
