The killer add-on for Firefox is Containers. This lets me run multiple instances of Gmail without them knowing about one another. I run Facebook and Twitter in another container and they don't know about anything Google.

My default profile is not logged into Google or Facebook or anything similar and uses DuckDuckGo for search.

You can set URLs to always open in a container. That gives me the benefit of cookies without having every website being able to detect them.

Firefox is fast, at least as fast as Chrome, for me. I did lose some extensions but the trend is very positive.
