On coveryourtracks.eff.org shows "Your browser has a unique fingerprint" with a red line under it, And on the section of hash it shows "randomized by first party domain", So I guess it is working some way.

Caused massive slow down when using ebay and other websites. Firefox identified it as causing slow down, task manager showed as 30% cpu usage for FF.

A very useful add-on. Thank you very much.

There is a little problem with it... this extension is used by a relatively small community. When a site makes a fingerprint of your browser, the part of the fingerprint is the used extensions... If you can't hide your extension, then the existance of it with some other parameters are enough to track you. IMHO

had to disable it because its slowing my browser down again. im sure its mozillas fault, not yours but pls look into it. (this has happened before and it was their fault)

Gooooooooooooooooood!

Yes

L'extenssion est super, elle manque juste a firefox sur android :)

Great extension, requires quite a bit of technical understanding, and the explanation for what different settings do could be better. Can have a significant performance impact with certain sites, but the extension, or Firefox usually notifies you when this is happening.
