Don't know if this is true.

FreedomWeb, an Irish company known for providing hosting for Tor "hidden services" -- services reached over the Tor anonymized/encrypted network -- has shut down after its owner, Eric Eoin Marques, was arrested over allegations that he had facilitated the spread of child pornography. Users of Tor hidden services report that their copies of "Tor Browser" (a modified, locked-down version of Firefox that uses Tor by default) were infected with malicious Javascript that de-anonymized them, and speculate that this may have originated with with FBI. Tor Browser formerly came with Javascript disabled by default, but it was switched back on again recently to make the browser more generally useful. Some are predicting an imminent Bitcoin crash precipitated by the shutdown.
