Firefox extension to obfuscate web page text▲235
Sometimes you might want to share a screenshot of the website you're on, without revealing the personal data that is visible at that time. With Obfuscate, you can make text unreadable without changing the structure of the web page. Hit the extension button or press Alt+Shift+O to activate for the current page.

Browser-based XSS scanner▲57
This is a simple single-file python program that can find basic XSS (cross-site scripting) vulnerabilities in a target url. Most XSS discovery tools use a payload refelection strategy in which payloads are injected in url parameters and the GET response is inspected for places where the payload content is reflected. This is a very low precision XSS detection strategy because most reflection does not support execution. This program uses a different approach, and instead opens the target url in a browser, tests alert(...) payloads directly in the browser context, and listens for an alert being…
