No.Tails provides upgrades every six4 weeks, thatwhich are thoroughly tested to make sure that no security feature or configuration gets broken. Updating add-ons in <span class="application">Tor Browser</span> might break the security built in Tails.

This second synchronization is made by sending HTTPS queries through Tor to several websites and deducing a correct time from their answers. You can see the list of websites that Tails can connect to in *[[!tails_gitweb config/chroot_local-includes/etc/default/htpdate.pools desc="/etc/default/htpdate.pools"]]*.
