I have been non-trusting of many Scripts for years now, call me paranoid, but if Facebook actually has the capability to just track you via Facebook Scripts that are executed on every site you have the option to Log in with Facebook or share via Facebook directly from the site, why would they not do it?
Google also tries to keep you logged by all means possible.
I block their Scripts, only temporarily allow if I need them, I don't keep cookies for longer than my current session except for Fastmail, I use VPN, have no DNS-Leak and WebRTC Detection turned off (last I checked you could not turn WebRTC Detection off in Chrome and the Extensions promising to do that were not working).
And that's also why I use Mozilla Firefox. Not because it's the technically better browser, but I have trust in Mozilla and their API just allows capabilities Chrome isn't capable of (that's why there is no NoScript in Chrome and no, there is no NoScript-Alternative in Chrome with the same features and capabilities, look it up).
Back when I used both Chrome and Firefox side by side, Firefox for example would turn off some Add-Ons/Extensions in Private Browsing Mode, while Chrome would not. I guess we all can grasp what most likely was the reason for it (Add-Ons/Extensions should not be able to obtain information from the user if in private browsing).
I am not saying that everyone should do it this way, I even recognize I am not the normal user and this is not for everyone, but complaining about Google because of Data Collection is like complaining about Facebook and the information they have about people while using it heavily and putting sensitive information up on it willingly. Get over it ;)
