This extension allows you to use I'm feeling lucky search and then click back to return to the existing results.
Simulates Google's I'm feeling lucky search, with a few small benefits. When you click back from the page you get to, you will be returned to the Google search results.
The default keyword is imfeelinglucky, but I recommend you click the app icon and add it as a search result manually. This way you can adjust the keyword, and optionally make it your default search engine.
Nothing is logged, the only people who will know what you are searching for is Google.
