I don't use that many Firefox extensions, just the ones which serve my immediate purposes, but from what I'd read about NoScript, I understood it to be an in-browser security guard of sorts - so I installed it...
A zillion options, with a never-ending webpage of instructions?! Java & AdobeFlash disabled by default?! STUFF THAT JACK!!!
It's now uninstalled. I do quite fine with what I already have, thanks very much
