Great improvement over "rigid" Greasemonkey :) Rated 5 out of 5 stars
Scriptish targets Fox 4.0 - were toolbar buttons replaces "soo oldschool" statusbar icons + are superior (just because can be placed were user wishes).
Statusbar can be left for Seamonkey or older foxes, but a toolbar button is something very desirable. :)
Hope this will always stay in active development :P
