Some of the main alternatives to Firefox are Google Chrome, Safari, Microsoft Edge, Thunderbird, or the good old Internet Explorer. Google Chrome is a preferred browser over Firefox since most consumption of content has moved from desktop to mobile, and in Android mobiles, the Google Chrome browser is pre-installed. Also, Chrome allows for syncing across devices and accounts and is extremely well integrated with Google apps. Firefox falters here because mobile users prefer to use a pre-set Chrome or Safari.
