Note, however, that torbutton currently targets Firefox 2 and doesn't claim protection under Firefox 3 -
i.e. xulrunner 1.9 or newer, which Conkeror requires - but work is ongoing to bring torbutton up to date.

An interim (and perhaps the safest) solution is simply disabling javascript, which, with regard to
anonymity, it is certainly safer than using something like Noscript.
