Overview
Product summary

The Netcraft Extension is a tool allowing easy lookup of information relating to the sites you visit and providing protection from phishing and malicious JavaScript.
What's new in v2.1.2?
• Improved caching of our feed to reduce network traffic.
Key Features:
• Protection against phishing sites — The Netcraft anti-phishing community is effectively a giant neighbourhood watch scheme, empowering the most alert and most expert members to defend everyone within the community. As soon as the first recipients of a phishing mail report it, we can block it for all users of the extension providing an additional level of protection from Phishing. Netcraft processes reports of fraudulent URLs from a diverse variety of sources and proactively searches for new fraudulent sites.
• Protection against malicious JavaScript — Prevent your credit card details from being stolen by shopping site skimmers or your computer's processing power being harvested by web miners. Netcraft has been detecting shopping site skimmers, web miners, and other malicious JavaScript since 2017. The extension blocks sites that we have found to be compromised with malicious JavaScript. Additionally, it detects JavaScript that we have identified as being malicious, blocks pages that use it from loading, and automatically reports them to Netcraft to protect the rest of the community.

The extension is able to read everything you view or submit through a web page. You are warned of this in the process of enabling the extension. Data being submitted by the end user is not required in order to alert the user to a threat. This extension is effectively harvesting personal data on the back of claiming to protect it. There are better options out there.
Please update the extension more frequently as it hasn't been updated since a long time, also updating the extension more frequently is very very important in order to block new types of malicious & phising & bad websites, so please get this extension updated more frequently with monthly or weekly updates for the same
This is the best anti phishing blocking extension that I ever have even better than Macafee web advisor, Norton safe web, Bitdefender traffic light and Kaspersky.
My antivirus everytime I google something and this netcraft extension tries to redirect my google search: "We've safely aborted connection to mirror2.extension.netcraft.com because it was infected with URL:Phishing." Its a URL phisher avoid at all costs.
Отличный продукт. спасибо разрабам
