Firefox: Previously mentioned AwesomeBar tool CyberSearch has seen an update that fans of the Firefox add-on will likely welcome with loving arms: searching the site you're looking at through Google requires just one keystroke now.
CyberNet blogger and extension author Ryan Wagner determined that a primary use of his extension, especially after recent Firefox upgrades that incorporated some of its original AwesomeBar search powers, was to search the site one was currently on. To make it easier, he's reduced the amount of typing to simply entering ">" before what you want to search the site for. So if you were browsing Lifehacker and wanted to search for other mentions of a particular extension, you'd type:
The next thing you'd see would be a Google search results page for site:lifehacker.com.au cybersearch firefox. If you were on our site and wanted to search Kotaku, you'd type >kotaku.com.au "fallout 3" or the like. That's a handy little upgrade, even if all it does for you is reduce the number of times you type site: into your address bar.
CyberSearch is a free download, works wherever Firefox does.
