These are the 5 ideas we hope to communicate that make Firefox standout versus Chrome:

* Firefox is leaner―its takes up less memory on your computer than Chrome,
　so you can run Firefox and do other tasks simultaneously. Meanwhile,
　Chrome seems to be getting slower and uses more of your computer’s memory.

* Firefox is independent. We just have a different reason for being than Chrome.
　Our goal is to help you access the entire Internet, not keep you inside our
　own ecosystem.

* Firefox gives you the most control over your data and privacy. See private
　browsing with tracking protection―which Chrome doesn’t have, or our new
　Focus browser on mobile.

* Firefox is not built by and for the largest advertising company in the world.
　So, there’s that.

* Firefox is built by non-profit Mozilla, whose mission is to preserve a healthy
　web in part by keeping corporate power in check. If you haven’t checked out
　what Mozilla is up to lately, it’s worth a look.
