The developers also warned about the remaining unfixed bug that allows you to organize the execution of JavaScript code in the "Safest" protection mode. The problem has not yet been resolved, therefore, for those to whom the prohibition of JavaScript execution is important, it is recommended to completely disable the use of JavaScript in the browser for a while in about:config by changing the javascript.enabled parameter in about:config.
