If you prefer Firefox, Multilogin has you covered.<\/span><\/b> Stealthfox is the Multilogin Firefox browser built on the real Firefox core \u2014 it behaves like Firefox but with one crucial difference: every profile you launch is completely isolated. That means you can use Firefox add-ons without leaking data between accounts.<\/span>\u00a0<\/span><\/p>
