If you find any problem installing it, this FAQ may help.

You can still download NoScript "Classic" (5.1.9) for Palemoon, Seamonkey, Waterfox and possibly other "vintage" (pre-Gecko 57) Firefox forks here: we'll do our best to provide security fixes as long as supporting browser still guarantee their own security updates.
