About this extension
Some websites have very strict CSP that may break userscripts that interact with the DOM. This extension allows you to disable CSP by default, with an optional whitelist in case some websites break (like banking apps). It will likely weaken your browser security, as it removes protections against cross-site scripting (XSS) and allows any website to make cross-origin requests. DO NOT USE IT ON SHARED DEVICES OR ANYTHING WITH SENSITIVE DATA, AS THE EXTENSION IS INTENDED FOR DEVELOPERS AND ADVANCED USERS WHO UNDERSTAND AND CAN MITIGATE THE RISKS.
