Very good- when used correctly Rated 5 out of 5 stars
I run the "Apollo! Pack!" collection and I put this one in there in addition to "Noscript." and it really should be used correctly like "Flashblock" or "Stop Autoplay." In my opinion "Noscript" may be the single best security add-on available. It may be a pain at first but it does remember the selections and in time your whitelist gets built and it is built to be a full time scriptblocker. "Quickjava" really shouldn't be the all-purpose scriptblocker IMO. It really should shine as a situational disabler- especially since it can also do flash, silverlight etc... Recently I was redoing a big folder of mine and I opened all 100+ tabs at once- but I didn't need to read anything, see any videos, hear any music... so for that situation this was perfect. "Noscript" is one of the top ways to have the most boring security scans in the world( since they will always come up empty) but this one when used situationally is a great compliment.This review is for a previous version of the add-on (1.7.2).
