If you remember the last post on Rapid Share Happy Hours which are the hours when rapidshare servers are not in heavy usage and the free visitors are allowed to directly download with out any wait time nor any cats crazy captcha. But the main question was how to find when these Happy hours are activated and its obvious anyone would not just open rapidshare every other hour just to check if Happy hours are activated or not.
Here is a new HappyChecker : A Firefox plugin which can help you out in finding the RapidShare Happy Hours. This new firefox application would check rapidshare on scheduled intervals and notify you whenever the Happy Hours are activated. This can help you out in getting rid of those captcha cats. The schedule of checking rapidshare is every 30mins and it works with the latest firefox version.
