Review for TotalSpoof by Harry Haller
Rated 2 out of 5 stars
I thought this was a good addon - until I tested it with the tool panopticlick.eff.org
According to this (eff=trustworthy) test, only one in 1151 browsers have got this user agent. This is no good tracking protection.
If you set the agent to "Mozilla/5.0 (Windows NT 6.1; rv:38.0) Gecko/20100101 Firefox/38.0", it's one in 135 browsers!
