Now sites can fingerprint you online even when you use multiple browsers

Here's one I found:
https://browserleaks.com/

I installed CanvasBlocker and though https://browserleaks.com/canvas shows me having a 100% unique id, it changes every time I refresh.
panopticlick's 'Hash of canvas fingerprint' changed every time I redid the test also.

https://browserleaks.com/javascript
with javascript enabled and then again disabled gives a good graphical idea of the power running javascript gives to the fingerprinters.

https://browserleaks.com/ip shows not only my ip but which dns server I am using also (but only with javascript enabled for their domain)

This is kind of old:

It mentions addthis.com. I'm using a hosts file based on one found here:
https://github.com/StevenBlack/hosts

What I currently have shows:

I am using the Unified hosts = (adware + malware) hosts file - 32,000+ domains get routed to the bit bucket.

One hopes that every little bit of security helps.
