LinkBars

How Link Relations Are Implemented
1.3, 2004-03-06

More browsers are beginning to support link relations. These are links that may not appear within the page itself, but describe connections such as "Next", "Home", or "Glossary", allowing simple, consistent navigation for all web content that defines these relationships.

Mozilla

Mozilla uses a toolbar with labeled icons, a Document menu, and a More menu.

Firefox (Firebird)

Firefox (and Firebird) requires the Link Toolbar extension, which uses labeled icons and a More menu.

Opera

Opera uses a toolbar with text buttons and no menus. The best matching link is used.

iCab

iCab was the first GUI-based browser to offer a linkbar (preceded only by the text-mode Lynx browser), and uses a toolbar with tiny unlabeled icons. Links that are not understood by iCab are available at ▼ [List of all standard links]>title (▼ [List of all standard links]<title for rev). The best matching link is used.

Internet Explorer

Internet Explorer requires the <LINK>-Bar extension, which uses unlabeled icons (link titles are used as tooltips), a [<LINK>-Bar] menu, and adds a popup blocker and a Google search.

* Note

All toolbar buttons use the first link that matches a button, except Firebird and the IE <LINK>-Bar which build a menu for the button if more than one match is found.
