You've come to this page because you've asked a question similar to the following:
I've been told that I can find it easier to navigate certain World Wide Web sites if I enable the link bar support in my web browser. How do I do that ?
This is the Frequently Given Answer to such questions.
You can find this answer in a different form (replete with lots of pictures) on Matthias Gutfeldt's web page.
You don't have to do anything.
These browsers come with built-in link bar support, and the navigation
links will be displayed automatically whenever there are
<link> elements in the current page.
Mozilla has built-in link bar support, but it is not always enabled. On the menu, under View | Show/Hide | Site Navigation Bar, pick either Show always or Show only as needed.
Install Site navigation bar, cmSiteNavitation, Link Widgets, or (if you have FireFox 1.4 or earlier) LinkToolBar.
Konqueror from version 3.3 onwards has bundled link bar support, but it is not always enabled. On the menu, under Tools | Document relations | Configure, pick either Always or When necessary (which should be "when appropriate").
If you have Konqueror prior to version 3.3, install rellinks.
If you have an older version of a browser that is mentioned here, then upgrade.
If you have a browser that is not mentioned here at all, ask its manufacturer whether it has link bar support, how to enable it if so, and to add it if not.
