Check XSS is a simple plugin, which would add a context menu of different payloads, such as XSS, CLRF and SQL injection. When you click on your desired payload on context menu, it gets copied to clipboard. And now all you have to do is paste it in on any input form on site.
The plug-in helps security engineers work more efficiently and easier.
