Re: Wishful thinking
Especially if you are using Firefox. They now have a farcebook container extension which "* prevents Facebook from tracking you around the web. The Facebook Container extension for Firefox helps you take control and isolate your web activity from Facebook." It creates a tab which hides everything you do in that tab from all the others you have open and vice versa. Just open about:addons search for facebook and make sure you use the genuine Mozilla extension.
