Tor Browser 6.0.4

Tor Browser 6.0.4 released with Mozilla’s servers ping fix

Tor Browser 6.0.4 released yesterday, finally brings Tor Browser users the latest Tor stable,, and avoids pinging Mozilla’s servers for system extensions. Pinging Mozilla’s servers was responsible for users getting an extension into their Tor Browser that resulted in annoying and confusing “Your Firefox is out of date” notifications on start-up (bug 19890). Thanks to Mozilla engineers, who fixed that issue as quickly as possible on their side, the extension is not shipped to Tor Browser users anymore since August 11 13:00 UTC.
