What mining option are you talking about, guys? I have no such option in my account, but I think I got it, it's in testing mode in some accounts. But what is it? Can some one who have it post a screenshot maybe? Is freebitco.in starting cloud mining or is it something else?
Sure it looks like this:
They haven't really said what it is yet.

Use your browser to passively mine bitcoin and receive mining rewards instantly to your FreeBitco.in account, credited every 5 minutes.
Please note that this feature is currently experimental and is only available to a limited number of users. Once it is rolled out across the website, we shall be able to increase the mining rewards further.
Click on START MINING and then adjust the number of threads and CPU percentage to use for mining. Usually the higher the number of threads and CPU capacity that you use, the greater your mining rewards will be. The default is to start with as many threads as the number of CPU cores that your device has and 100% CPU usage. Lower the CPU usage when you are using the device for something else and increase it to 100% when your device is idle.
Mining will stop when the STOP MINING button is clicked or this browser tab is closed. You can use your account to mine from multiple devices at the same time. Mining rewards are automatically credited to your account for every satoshi that you earn and the TOTAL MINING INCOME in this page shows the total rewards that you have received from mining since the beginning.
