★☆☆☆☆ Firefox user 5905964 · 8 Oct 2025 · v2019.7.18Malware. Timezone monkeying (nonsense values) makes you very, very unique and very, very easy to track! Says privacy on the tin, but achieves the opposite.

★★★☆☆ Firefox user 16480293 · 17 Jun 2025 · v2019.7.18Appears to be interfering with some websites' login procedures. Trying to login to artstation with this enabled results in an infinite loading screen.

★★☆☆☆ Marf · 23 Dec 2024 · v2019.7.18Used to be ground breaking, but it has not been updated since Jul 18, 2019. Now it seems to break a lot of sites. I wish it had a better interface so we could toggle global settings of what we wanted enabled and disabled. It seems with a lot of the new privacy laws, browsers are starting to build these features in.

★★★★★ Hexapool · 10 Nov 2024 · v2019.7.18It automatically blocks the tracking headers. Great !

★★★☆☆ Padua · 1 Oct 2024 · v2019.7.18Good extension, but breaks panning on Google Maps. Would be nice if this extension gets an update, with a fix.
