purpose? Rated 2 out of 5 stars
I have logical problems concerning the purpose of this:
IF "Firefox is secure enough by default" than what would be the point in blocking scripts? Especially if, as it seems to me, there is no way to differentiate between scripts. (At least my intuition did not lead me to any UI element to do so.)
You just allow or deny execution of ANY scripts on that page. So as to the parania part: Users might get paranoid with a programm, that does neither tell them, what (domains from) scripts are trying to be loaded or have been blocked from that.
Despite these logical problems the addon seems to do it#s job just fine and block any script on a given page. So you gained hassle without hassle, because many sites have their own scripts and 3p-scripts loaded. I simply do not see any point in blocking all scripts point blank. THAT in fact, might as well be considered paranoid in a strange limited way ...
