Firefox Extension Bookmarks Synchronizer

I am trying out the bookmark synchronizer extension for firefox. The idea sounds great, but there are no documentation. This is how I got it to work:

1. I setup a WebDAV folder on my server (more secure than clear text FTP
2. in the extension option, I selected "HTTP" as the protocol, and enter my host name, user name, etc in the dialog box.
3. I downloaded the XSL and CSS from the author's site and place those two files, xbel.xsl and xbel.css into the same directory on the webDAV directory. To download those file, click here for the CSS and here for the XSL
4. I also use the advanced tab and added to the style tags box the following: <?xml-stylesheet type="text/xsl" href="xbel.xsl"?>.

Also see all of the extensions that I used here.
