Overview

Product summary

Review the store description, core capabilities, and common use cases.

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.

This seems to be one of the best plugins on the market for finding all kinds of malware! Excellent service! Would be a bonus if the malware file could be pinpointed in the plugin but this is great in any case!

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.
