The Link Toolbar is now called the Site Navigation Bar and is accessible by selecting the View menu then Show / Hide then Site Navigation Bar then Only as Needed. There are many bugs in the Site Nav Bar, see bug 103503 for a list of bugs currently filed against it.
There is also a Link Toolbar for Firefox that works very nicely.
Do not install the link toolbar! It won't work!
This update includes a massive rewrite by Tim "Tool-Man" Taylor. Tim has rewritten the guts of the toolbar and given it a spiffier image. I attempted to add localization support to the package but something seems to be horked.
There has been alot of discussion on bug 2800, so check that out. Remember, please stick to the implementation of the toolbar and not gui. The focus of the bug is the guts, not the GUI.
Now up to version 1.1. The instructions at the top of the page will always install the latest version. Changes:
The Link Toolbar will now properly displays all links from Evil Tests: LINK - 1 and Evil Tests: LINK - 2 which are the first two test links from bug 2800. I still have to work on getting the parser up to date with the link specifications contained in the bug though.
Unfortunately using the link toolbar with modern will not display the link titles properly. Until I get out from under some homework I won't be able to fix this. The current workaround is to use classic instead of modern if you are using the link toolbar. Thanks to googolplex on #mozillazine for pointing this out.
Doron ( #mozillazine ) requested a screenshot of the link toolbar so there it is. When a page has the <link> element the link toolbar shows that link in the toolbar by highlighting the appropriate button. Link rel types I currently do not support show up under the "misc" button. For more information on the <link> button type see HTML4.01 LINK element specification.
Some people are seeing a blank toolbar after installing the XPI. If you get this could you send a bug report to the above address with the build id and the install method? I designed the XPI to work with Mozilla builds that are using the new XUL syntax.
This is a first pass at fixing bug 2800. I haven't polished it at all and it doesn't support Link HTTP headers, so don't complain too much. It does work. Give it a spin and so-forth. I may not be able to work on it for a long time, so patches are appreciated, but I may not be able to get them integrated very quickly.
The best place to try out the toolbar is at The World Wide Web Consortium.
