- Open FF
- Install the universal search addon if you haven't already
- Enable the Browser Toolbox
- Open the browser toolbox
- Switch the debugger to the iframe context using this funky little menu button:
- Do this in the console:
window.app.searchUrl = 'https://your.server.com/?q=';
- The query term will be escaped and appended to the
searchUrl
Note that this modified iframe context is bound to the chrome window, so you should be able to retain the server link as long as you don't close that window or switch windows.
