Unless you are using some sort of VPN or proxy that's constantly changing your IP as you're browsing, and a browser that consistently changes or masks fingerprintable information and wipes all persistent tracking beacons, then what you're doing is not even remotely sufficient to evade tracking by any entity. What you're doing is definitely not enough to avoid Google or Facebook.
At this time I believe nothing can do this with 100% effectiveness. The closest would be to use Tor Browser and never disable NoScript and only use sites that don't rely on JS... but even then there are many theoretical workarounds, many more to come in the future, and probably various unknown techniques currently being tested or deployed.
I know enough about the technology to realize it saves me a lot of time, effort, and stress to just accept my fate. I no longer include ad networks or big tech companies in my personal threat model, even though I dislike what they're doing.
