Massive pain in the rear Rated 2 out of 5 stars
Makes browsing safer, but it can make it a massive pain to get some sites to work right, even after whitelisting. I used it for a while and decided that marginally safer browsing simply wasn't worth the trouble of tuning noscript every time I opened a new website. I have a lot of sites I visit often, but I'm pretty frequently on unfamiliar ones too, and it slows me down considerably when I'm trying to actually use a website.
Sorry, but no thanks. I'd love a plugin that stopped dangerous scripts but left low risk ones alone, working of the model of adblock, but this simply isn't that. I would not recommend it for most users.
