Firefox and Firefox Focus.
These two browsers share many things. Developers, browser engines, the ability to allow us to easily browse the internet. Even the names and logos are similar.
However, I will say this: these two browsers are very different, despite the similarities.
The Brave browser and Firefox Focus are both privacy browsers with millions of active users across the globe.
Both browsers also retain enough functionality to keep up with the "ease-of-use" and convenience factor of more mainstream browsers such as Safari and Google Chrome.
