Manage cookies in webpages

Cookies are small data files that store information in connection with a website. For example, a cookie may be created to store the contents of an online shopping basket, or to confirm that you are logged in as you browse the pages of a site. When a cookie is set, the sequence of events is the following:

During first contact, the website offers you a cookie for a specific domain. If you accept the cookie, it is saved on your computer. Every time you make contact with a resource in that domain, the browser sends the cookie.

Cookies can be used to construct a profile of your browsing habits, and are therefore regarded by some as a privacy issue.

If no expiration date is assigned to it, a cookie expires at the end of the session, when you exit the browser. A cookie that expires at end of session is called a session cookie.

Set your cookie preferences

Setting preferences gives you control of how Opera handles cookes. The default settings is to accept all cookies. To change this:

  1. From the main menu, select 'Settings'.
  2. Click 'Privacy & security' in the sidebar.
  3. Under 'Cookies', select an option for handling cookies.

Click the 'Manage exceptions' button to set site-specific preferecnes.

Manage images in webpages

You can control how Opera handles images on webpages. You can opt to display all images or not, as well as set site-specific image preferences. To change image settings:

  1. From the main menu, select 'Settings'.
  2. Click 'Websites' on the sidebar.
  3. Under 'Images', select an option for handling images.

Click the 'Manage exceptions' button to set site-specific preferences.

Manage JavaScript in webpages

JavaScript is a scripting language used to add functions to webpages, such as manipulating browser windows. In rare cases, JavaScript may be used intrusively to perform certain actions you may find annoying. For these cases, you can turn it off completely, but note that this will often mean that some webpages will not work as designed.

To change JavaScript settings:

  1. From the main menu, select 'Settings'.
  2. Click 'Websites' on the sidebar.
  3. Under 'JavaScript', select an option for handling JavaScript.

Click the 'Manage exceptions' button to set site-specific preferences.

Manage plug-ins in webpages

Many multimedia files on the web require third-party software, known as plug-ins, to be played. A common example is a media player to play videos or music. When Opera detects the need for a plug-in that is not installed, it offers to take you to a site to download it, or offers to download it for you.

Opera, by default, runs any plug-ins installed on your computer automatically. But, you can control how Opera handles plug-ins manually, if you wish. To change plug-in settings:

  1. From the main menu, select 'Settings'.
  2. Click 'Websites' on the sidebar.
  3. Under 'Plug-ins', select an option for handling plug-ins.

Click the 'Manage exceptions' button to set site-specific preferences.

To disable plug-ins, and prevent Opera from running them, click 'Disable individual plug-ins…" This will open the Plug-ins page, giving you a list of plug-ins that Opera is using. This list includes details about what version of the plug-in you have installed, and a brief description of the plug-in's use.

Click the 'Disable' button to prevent Opera from using the plug-in. This does not delete the plug-in from your computer.

Tick the 'Always allowed' checkbox to override site-specific exceptions.

Install and configure the Java plug-in

Java may be required to display web content properly. It is a common tool used by some web developers. The instructions that follow will help you install the Java plug-in for viewing Java content on Opera.

To install Java, download the latest version from the Java website. Click the 'Agree and Start Free Download' button to begin downloading the set-up file. Then, open the set-up file and follow the on-screen instructions.

Manage pop-ups in webpages

Opera will try to distinguish pop-ups that you have requested, such as log-in pages or similar, from pop-ups launched automatically from websites, typically advertising.

By default, Opera will block pop-ups you have not requested. You can control how Opera handles pop-ups. To change pop-up settings:

  1. From the main menu, select 'Settings'.
  2. Click 'Websites' on the sidebar.
  3. Under 'Pop-ups', select an option for handling pop-up windows.

Click the 'Manage exceptions' button to set site-specific preferences.
