I'll try to install tear tomorrow and test a little also. My first guess would be to try what hvacengi tried and edit the uri-action-defaults.list file rerouting http. I'll try that anyways but from what he said that might not work. A quick glance shows the plugin for bookmarks is registered in /usr/share/applications/hildon-navigator/hildon-task-navigator-bookmarks.desktop to a libtn_bookmark_plugin.so so even if hardcoded, maybe nokia released source for that?
