Settings > Preferences > Advanced > Content

Control the display of webpage content.

Press Page Down and Page Up to switch slides

Multimedia

Disabling GIF and SVG animations will make animated images in these formats display as ordinary graphics.

Disable sound in webpages for example if you listen to music from your computer and do not want to be interrupted by sounds generated by webpages.

Note that disabling sounds in webpages will also disable Voice.

JavaScript options

JavaScript is a scripting language used to add functions to webpages. JavaScript may in rare cases be used intrusively and can therefore be turned off completely, but note that this will also disable well-intended use.

Click "JavaScript options" to prevent JavaScript from performing certain actions you may find annoying, such as manipulating browser windows.

If you have User JavaScript files on your computer, you can select one or multiple User JavaScript folders to use for local dynamic altering of websites.

Style options

Display

If you disable frames or inline frames, pages that use them will display alternative content if available.

To see how webpages with frames are constructed, enable frame borders. When you view framed pages, the currently active frame will always be outlined.

You can choose whether to show forms and scroll bars in webpages in the standard style or allow websites to style them differently.

My style sheet

Click "Choose" to select a personal style sheet to use. Note that the default "user.css" is a blank file. This style sheet will not be listed on the Style menu.

Presentation modes

Opera has two modes for viewing webpages. "Author mode" lets you see a webpage as its author intended, while "User mode" lets you view the page in your own style.

You can select which mode to use as a rule, and you can edit display settings for each mode. Note that "My fonts and colors" and "My link style" refer to the settings in the Webpage preferences.

Tip: To switch between the two modes while browsing, press Shift+G, or use the drop-down button on the View bar.

Java

Some sites use Java to offer interactive content on webpages. If you do not have Java installed, Opera will automatically offer to take you to a download site when you encounter such content.

Plug-ins

Many multimedia files on the Web require third-party software, known as plug-ins, to be played.

You may completely disable plug-ins. Then you will only see files that Opera can display by itself.

Site preferences

All the above preferences apart from presentation mode are available as site preferences. From the general content preferences you can also directly access all site preferences and all blocked content.
