About Tamper Dev:
This is the new version of the extension previously called Tamper Chrome,
but now supports multiple browsers, and does not require an auxiliary app.
This extension provides functionality similar to Burp Proxy, MITM Proxy, OWASP ZAP, Tamper Data, and Postman Proxy,
but without the need of additional software, with full support of HTTPS connections, and trivial to set-up (just install).
