Gauthampai said "Sometimes, 'we want to feel lucky' in the search result page as well. ;)" and here we are.
The greasymonkey feellucky makes it possible for us to bookmark search results as lucky. If you have made a particular query lucky by clicking on the make lucky link, the next time you put the same query you get lucky.
To install this greasemokey the firefox browser with greasemonkey is needed. To install just click on Install feellucky. The feel lucky script makes use of GM_setvalue and GM_getvalue to store the queries that need to be lucky. So the lucky feeling is limited to the system on which the gresymonkey is installed.
To make it useful for a wider audience, the lucky queries need to be stored on a server.
