Additionally, the browser is not optimized for optimal performance, security, and user experience.

Para proteger tus datos, debes evitar que Firefox las guarde. \ud83d\udd10\u270b<\/p>\n<p>To do this, click the three horizontal lines in the top right corner and select &quot;Settings.&quot; Then, go to the &quot;Privacy &amp; Security&quot; tab on the left and scroll down to the Passwords section.<\/p>\n<p>Here, uncheck the box next to &quot;Ask to save passwords.&quot; Also, click &quot;Saved Passwords&quot; and delete any passwords stored in the browser. \u26a0\ufe0f\ud83d\uddd1\ufe0f<\/p>\n<p>Just make sure you don&#039;t delete all your passwords before confirming that you have them memorized or saved somewhere safe.
