Firefox is a free web browser from Mozilla. It is one of the world's most popular browsers, along with Google Chrome and Internet Explorer.

What is Firefox and do I need it?

Firefox does its best to ensure that you have the best user experience. Firefox has built-in tracker blocking features to block trackers and scripts such as social media trackers, cross-site tracking cookies, fingerprinting, and crypto miners. The browser also allows you to add tweaks to maximize your online privacy.

What is the difference between Chrome and Foxfire?

Both browsers are very fast, with Chrome being a little faster on desktop and Firefox a little faster on mobile. They're both also resource-hungry, though Firefox becomes more efficient than Chrome the more tabs you have open. The story is similar for data usage, where both browsers are pretty much identical.
