The same profiling is done from Safari and other Chromium / Blink browsers that have the "awesome address bar"
I have read that when you visit a page with Analytics (which is like everywhere) Chrome has special handling so as to give them a more complete dataset without it being the browser that is officially collecting it.
It's simple and straightforward to disable the autocomplete functionality in Chrome.
Not sure I follow. Why can't chrome just detect whether you entered a URL or not? If URL, load without sending to Google. If not a URL, send as search to Google.
And who can decrypt that?
In Firefox, back when it was introduced in Fennec somewhere around 2007 or 2008 (I don't know how it is now), you'd need 2 passwords. One to log in to your Firefox account and gain access to your encrypted data, and one to decrypt the data. It is feasible a nationstate can get access to your encrypted data, but it isn't feasible they are able to decrypt your data.
