If you've ever wondered about a web site, Netcraft is the place to start.
My basic question is, Is that website safe?
Before unblocking NoScript, I always go to Netcraft first.
How old is that site, what's the risk rating, does it have JavaScript malware? Netcraft knows. Netcraft can and will block BadJava

excellent extension to find out what a site really is made of. Analyze all things related with Netcraft with ease.

It's like free guardio :)

This extension has been with us a long time. Major props for keeping it alive, devs!

Looks nice but is it only me or site info is constantly being refreshed/blinking.

Netcraft is usually reacting much quicker than default browsers' systems when finding a new site. For all who's reported malicious sites and were rejected, I'd recommend ask for re-analyze. From my experience, if a phishing site wasn't properly labeled after the report, they usually correct it after complain.

I believe that the public benefits from this application and endorse any effort to recognize Netcraft as a great contributor to the welfare of the internet worldwide. Robert Alle

It's nice to have a program that informs me of a bad site 99.999% of the time. And it will take info of a found bad site from from it users. Check, then place it place it in their program within hours.
Netcraft DOESN'T slow down or lock up your computer like Micro$oft use to, with safe site checker!
THANK YOU Netcraft

This is the best antiphishing addon it also comes with other protections

One of the best extensions for safe surfing, but breaks the layout on rambler.ru Also false positive for yandex.ru/video/ after search something there.
