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

Mode settings

To adjust settings for "Author mode" and "User mode" modes, go to Settings > Preferences > Advanced > Content, click the "Style Options" button, and select the "Presentation Modes" tab.

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 for fonts in the Webpages tab of Preferences.

Display frames, forms and scrollbars

To control the display of frames, forms and scrollbars, go to Settings > Preferences > Advanced > Content and select the "Style Options" button.

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.

Use your own style sheet

Go to Settings > Preferences > Advanced > Content and 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.
