Opera

When a Web page appears to display incorrectly in Opera, there can be various reasons for this:

• They may be badly written or written specifically for certain browsers without taking other browsers into account
• They may block Opera, either directly (by actively checking if you are using Opera) or indirectly (by actively looking for "supported browsers", and if Opera is not in that list, don't send anything useful)
• It could be using a feature not supported by Opera yet
• There could be a bug in Opera
• There could be a setting in Opera which needs to be changed

To ensure that Opera is set to display pages the way the author indended, please make sure that the following settings are correct:

• Enable images in Tools > Preferences > Web Pages
• Enable plug-ins, JavaScript and Java (for those who have installed Java support) in Tools > Preferences > Advanced > Content
  (note: Java and JavaScript are two different technologies. JavaScript is supported without the need for extra downloads.)

There are other things you should enable as well:

• Go to Tools > Preferences > Advanced > Network
• Enable "Automatic redirection" (this is widely used)
• It is also recommended that you enable "Referrer logging"

For sites that require logging in, referrer logging is important, but you should also:

• Enable cookies in Tools > Preferences > Advanced > Cookies)
• Set Opera to "Accept all cookies" for both normal and third-pardy cookies
• Make sure cookies aren't blocked under "Manage cookies..."

Opera also lets you control directly how Web pages are displayed. This is done in Tools > Preferences > Web Pages and Tools > Preferences > Advanced > Content. The settings you should check are:

• Set default zoom to 100%
• Enable "frames" and "inline frames"
• Set "Author mode" as the default mode in Content > Style options
• Remove any user style sheets in the "My style sheet" text field in "Style options"

Remember to set Opera to display the page according to the settings described in this article:

• Displaying pages the way the developer meant them to be displayed
