"Still the Best"
It's snappy, loads pages fast, very secure, the most customizable browser available, provides the ability to add and change advanced settings, and Firefox provides excellent accessibility features for individuals with disabilities.
There isn't a Firefox OS
I have gotten more out of using Mozilla Firefox in the past 6+ years than I have from any other piece or type of software, ever. Even OS's.
Mozilla has consistently delivered a solid, safe, and very fun to use product from day one, and I expect nothing less from them in the future.
