Yet another Mozilla Labs Prospector experiment called initial stroke designed to improve search and content discovery in Firefox. Home Dash removes UI elements like the location bar, search bar, and tabs from the Firefox browser interface, and you’re left with a lonely Firefox logo that displays the dashboard.
initial stroke displays the top 24 websites on the right side based on your browser behavior, on the left corner a search box appears where you can type and show top matching websites instantly. By hovering your mouse cursor over the top site, you can see the instant preview of the page.
Home Dash offers search icons like Google, Bing below the search box where for example you can click on the Google icon and type query in the search box and get the search results on the right if you want you can enable a second search by clicking the Bing icon to get results side by side with Bing.
you can try initial stroke try it if you are using the latest Firefox 4 Beta.
