Get paid to search yahoo!

I was browsing around last night and stumbled across a forum post, In the post they were talking about how they just made money by searching yahoo, It got me interested as I thought you all might be interested. Anyways the link is here http://cooloffers.50webs.com/msf/

When do you get paid?
They pay out every 30 days, you must have a balance of at least $20, and they either send it via paypal or deposit it to your bank account.

How does it work?
Basically it just edits your firefox search bar in the top right of firefox and links it to your account with the site, thus when you search it knows and you get paid.
