Firefox readies tougher stance on cookies
Up until now, only Apple’s Safari browser had blocked third-party cookies by default. Last week’s release of Firefox 22 to its developer’s channel also came with the feature, indicating that the option will soon make it to all Firefox users.
Firefox 22 Aurora (download for Windows, for Mac, and for Linux) blocks third-party cookies by default, putting the ad industry on notice that browsers are about to start looking askance at them. While Safari has had the feature for a long time, no other major browser has supported it until now.
