Access Wikipedia Again
As you're probably already aware, today (Wednesday 18th January), Wikipedia have put up a blackout notice on their English language website.
There's a lot of alternatives such as using the French (or another language) version of Wikipedia to get your information, and just translate it back to English, but there's a fundamental flaw in this, the other language sites generally don't contain the same information at all!
Instead, here's a bit of Javascript that you can put into your addressbar once you see the blackout notice to get access to Wikipedia back. Note that you will have to do this for every page..
javascript:(function(){var hiddenEles=document.body.getElementsByTagName('div');for(var i=0;i<hiddenEles.length;i++){hiddenEles[i].style.display='block';}document.getElementById('mw-sopaOverlay').style.display='none';})();
If you wish, you can always get the same effect (due to the overlay being presented in Javascript), by simply disabling Javascript in your browser!
