Today I created a simple extension for WebRunner. I believe that this will only work with the latest SVN version from svn.mozilla.org

To install, unzip the file into the extensions folder inside your webrunner profile. On Linux it's in ~/.webrunner/XXXX/extensions (Where XXXX is a randomly generated name)

Currently implemented features:

• Adds "Copy link location" to the context menu for links.
• Adds an About:Config option to the webrunner application menu.
• Adds basic security feedback UI: simple status icons indicate secure/insecure states

Note: Icons come from the Silk icon set at famfamfam.com.

Update: Tonight I created a gtalk.webapp which makes Webrunner use the Google Talk widget (Flash required) - the file is attached below for anyone who might be interested.
