I created something similar yesterday afternoon [0]. Instead of opening a new tab, it just requests pages through a hidden iFrame and drops the headers so the request goes through.
It doesn't click on anything, because it would be awkward if this by chance started sharing things on logged-in Facebook profiles etc. I plan on adding sequential requests over the weekend so the traffic is more realistic.
It's open source and on Github, so you can download, install and modify it from there if you wish [1].
