Cookies are small text files that are sent by websites that you visit to recognise who you are when you return there. There files are stored on your computer’s hard drive, and are read by your web browser.
Adobe uses a particular type of cookie called a ‘Local Shared Object’, which is typically collected if you watch a video for example that uses the Adobe Flash media player, i.e. an embedded YouTube video on a page that is being played via Flash. Please note that these types of cookie will not be found on iPads, which do not support Flash.
Have a look at Adobe's website if you want to control Flash cookies on your computer. If you’ve got a Firefox browser you can also get an add-on to detect and delete Flash cookies.
There are a number of options available so that you do not have to store any cookies at all. You can either set your browser so that it will not accept and store any cookie, or if you have a little more time and knowledge you are able to allow only certain ‘trusted’ sites to store cookies on your computer. These sites may include this site, the site where you carry out your online banking, or possibly your favourite news service.
It’s worth bearing in mind that if you decide to delete all of your cookies, then you will likely have to re-enter all of your usernames and passwords on all of the sites that you visit, which you previously didn’t even have to think about. As mentioned before, cookies can be a real asset to your web surfing experience.
The Information Commissioner’s Office (http://www.ico.gov.uk/) provides some advice about cookies and their use, it also provides a link to ‘About cookies’ (www.aboutcookies.org) which is run by the law firm Pinsent Masons. This website provides even more information about cookies, it also details how you might delete any cookies that you find and it shows you how to allow those trusted sites to store their cookies on your computer.
