Firefox Search Plugin
wURLdBook's Firefox/Mozilla plugin is a great tool to keep you connected to your important wURLdBook content. You can do all the searches such as alias resolves, web reference content searches and RSS feed searches, with this plugin as you can with the search bookmarklet and wURLdBook's textfield search.
You still need to know wURLdBook's idiosyncratic searching method to harness its full power though. But, I'm confident that you can do it.
Once you have clicked the one of the images and installed the plugin you need to go to the top right hand corner of your Firefox window and select the wURLdBook search plugin from the pull down list in order to use the plugin.
That's all there is too it.
