Cookies are your enemy and should be removed daily, or even per session.
A good start would be to install 2 extensions in order to control whats loading when visiting sites.
Cookies combined with scripts running in full work to track and build analytics for the very filter systems you are having trouble with.
When you combined this (cookies and scripts) with your default “User Agent” values/settings – your internet use and browser become unique and very traceable.
Exactly what you don’t want.
Extensions to install
1: Noscripts
2:UserAgent Switcher 0.5.0

Ipleak.net

Once the check is complete you will see a bunch of information pertaining to you connection. (Very Useful)

Another thing that could help is to use an alterantive DNS server.
