Take Browser extensions as an example. Some extensions are claiming they will improve your user experience on trading sites. Except they may read at the same time all your typing there. Stick with the ugly user experience, youll be safer.
My advice is, make sure you do NOT download any crypto extensions. Browser in Private mode where usually extensions are disabled. Or use a fresh browser only for this. You can take a look at Brave which is a Blockchain native browser with built-in wallet
