Do You Use a Permanent Cookie Blocker/Eraser?

[kyphysics]

I've been learning about Evercookie and permanent cookies that websites will use nowadays to make it very difficult to remove a cookie.

But I've heard of browser add-ons that can erase/block these permanent cookies.

Anyone use them and/or know of a reputable one they'd be open to sharing? Any pros/cons?

Yes, I do use a cookie eraser: Self-Destructing Cookies. It is an add-on in Firefox. Don't know if it is the best nor the worst, but it works for me.
It is amazing how many cookies (permanent or not) get onto your system from third parties you've never ever heard about. The main con there is: you'll be asked to enter your credentials every time unless you whitelist the site. But is that really a con.
