Strange URLs for Google searches

[synaeus888]

Whenever I do a google search using Centaury, I get this sort of URL:

http://www.google.com/#spf=1607991520641

Mypal gives this:

https://www.google.com/

Firefox 52.9.0 gives this:

https://www.google.com/?gws_rd=ssl

I am curious about the #spf=1607991520641 As it changes everytime I do a search, I am assuming this is a Google tracking number....but why only on Centaury?

No idea, i do not use google and avoid it at all.
