This add-on is the best on the Firefox Store.(For a budding dev)
It's can show 3 things about a site.
The location, registrar and the safety which is kinda a hit or miss.

It worked really well, the accuracy was also quite good. The user interface is simple and minimalist without any unwanted information or features.

Simple yet efficient extension to check for malicious websites. I liked how the extension uses just the URL without accessing the webpage content. The results were also fairly accurate.

Very well designed extension. User friendly interface and the results were also accurate. The load time can be improved.

It helps to detect malicious phishing websites from the URL using machine learning.
