A cookie is a file containing an identifier (a string of letters and numbers) that is sent by a web server to a web browser and is stored by the browser. The identifier is then sent back to the server each time the browser requests a page from the server.
Most browsers allow you to refuse to accept cookies. For example:
- (a) in Internet Explorer (version 9) you can block cookies using the cookie handling override settings available by clicking “Tools”, “Internet Options”, “Privacy” and then “Advanced”;
- (b) in Firefox (version 16) you can block all cookies by clicking “Tools”, “Options”, “Privacy”, selecting “Use custom settings for history” from the drop-down menu, and unticking “Accept cookies from sites”; and
- (c) in Chrome (version 23), you can block all cookies by accessing the “Customise and control” menu, and clicking “Settings”, “Show advanced settings” and “Content settings”, and then selecting “Block sites from setting any data” under the “Cookies” heading.
Blocking all cookies will, however, have a negative impact upon the usability of many websites.
If you block cookies, you will not be able to use all the features on this website, including but not limited to making donations.
You can also delete cookies already stored on your computer. For example:
- (a) in Internet Explorer (version 9), you must manually delete cookie files (you can find instructions for doing so at http://support.microsoft.com/kb/278835);
- (b) in Firefox (version 16), you can delete cookies by clicking “Tools”, “Options”, “Privacy” and then “Show Cookies”, and then clicking “Remove All Cookies”; and
- (c) in Chrome (version 23), you can delete all cookies by accessing the “Customise and control” menu, and clicking “Settings”, “Show advanced settings” and “Clear browsing data”, and then selecting “Delete cookies and other site and plug-in data” before clicking “Clear browsing data”.
Again, doing this may have a negative impact on the usability of our website.
