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.

• Detailed site reports – simply click the Netcraft logo to access a wealth of information about the sites you visit, helping you to make informed choices about their safety.

• Conveniently report suspected phishing & fraudulent sites – At the click of the button you can report suspected web forgeries to Netcraft, helping to protect the community. Netcraft operates an incentive scheme for Phishing site submissions, including iPads, backpacks, mugs, and more…

Hello, I hope you're having a splendid day! I am currently seeking opportunities to expand my business operations by investing in extensions with a significant user base, beginning from 50,000 users and up. No matter if your extension has a modest user base or counts its users in the millions, I am interested and ready to negotiate a purchase. If you are in possession of such an extension and looking to turn it into a profit, please consider reaching out to me. We can discuss the price and proceed with a transparent and secure transaction through a trusted escrow service based in the United States. It's great that Google allows the transfer of extension ownership between accounts, so your Google account ownership will remain intact. If you have any needs, please contact us via the following contacts Whatsapp: +1 (248) 896‑8035 Telegram:
