I've been browsing the internet for 15 years with 3rd-party cookies disabled. I never had ANY problems with any website - no idea if there would have been more functionality with 3rd-party cookies enabled. But then again, how can functionality depend on THIRD parties? Also activated the setting for my girlfriend years ago, no complaints so far. This feature should really be the default for any browser and any user. Too bad Android Chrome doesn't have such a setting. Too bad for Google I'll use something else instead.
