The Log Search Bar plugin for Selenium IDE has been updated to v1.1. This version works around a bug in Firefox to support older 3.x versions of Firefox and adds some internal improvements. Thanks to Bob Zakes for providing helpful comments about circumstances when it did not work. The user interface was not changed.
Until AMO approves it, you need to manually get the update from the Firefox addons website. As usual, feel free to leave comments, improvements, advise, criticism, problems…
