@keartland You can use whichever you want, but #Firefox was before #Opera, before #Safari, before #Chrome, and before#Edge. This ties to why my team loves UNIX/DOS-3.1 (meaning no Java6<, Python3<, .Net3<, nor Swift3<) more than all other operating systems and internet programs, and for users to legally provide their own services, not ginormous domains doing so. Can you tell why? Honestly, Chrome, Edge, Safari, Opera, and all other modern #browsers would not exist or be so little without Mozilla Firefox's development. Right #phone services? Virtual private networking ( #VPN )? #Thunderbird?
