Hmm, if I wanted to blend in with John Q. Public I guess I should dump Linux altogether and go back to use Internet Explorer in a bone stock configuration on MS Winblows, ... (?!)..
Coincidentally there is an article in this month's 2600 regarding this and I feel like an idoit for forgetting:

If you don't already read 2600 then I would recomend taking a look at the online content at least.

You don't need to use a highly customized one.
I use this:

You can spoof any user-agent and it doesn't really get in the way (I will get random warnings every now and then about using a old version of IE and get confused before I remember I'm using it lol)

That only spoofs the user agent string though, which is only part of the battle. For that matter even the plugin I linked to doesn't prevent "browser fingerprinting" or IP address tracking.

The only "real" way to identify a computer is to use an encrypted connection with unique digital certificates at both ends. Anyone who succeeds in establishing a connection must be in possession of a certificate that can be traced uniquely to him. The crypto transport further assures that the messages will be received as-tendered.

VPN, of course, is a de facto method of doing this, which also has the advantage of being transparent to both parties. If properly secured (i.e. "don't use PSKs == passwords"), the tunnel is reliable but invisible. It can be implemented in hardware.
