The following method is cross-platform, it works also for other SE sites. Oh, and it is also cross-platform in the sense that it works for other operating systems.
Based on this meta.SO comment, I have created the following script that automatically starts mining every 15 seconds, from the moment of invocation:
(function(fn){setInterval(fn,15e3);fn()})(function() { $.get("/unicoin/rock").done(function(obj) { console.log("Mining: ", obj); var key = obj.rock; $.post(["/unicoin/mine?rock=" + key], {fkey: StackExchange.options.user.fkey}); }); });
As this is a script, you should execute it on the SE domain where you wish to accelerate your mining. In Firefox, you can open the Console by pressing Ctrl + Shift + K. In Chromium, simply press F12. Paste it and gain coins! To stop it, simply refresh (or close) the page.
Note: you should not execute this multiple times. That would make the Unicoins economy collapse and therefore measures have been taken such that you cannot get coins in that case.
