Its latest edition is the Search Perks incentive, which joins Live Search Club, Search and Give, and Live Search Cashback promotions in recent months. Microsoft is getting a little trickier with its latest effort -- you not only have to use Microsoft's Live Search, but you also have to use its Internet Explorer Browser which is bad news for Firefox stalwarts. To join the promotion, users must download a small program. You can't download the program or view the true SearchPerks site from Firefox or Opera browsers. Once you get the program, it tracks your searching and gives you one ticket per search query. You can earn up to 25 tickets a day. In April, users can cash in the tickets for prizes or to give money to charity. Microsoft has not announced the prizes yet, but one of them might start with "V" and end with "ta" according to rumors.
