Funny
Funny because that's how we ended up with Firefox. It was touted as so much faster and lighter than the Mozilla Suite (now called Seamonkey) when in reality it was almost exactly the same, but work pivoted over to Firefox.
As a result, we don't all have an HTML editor installed as part of our browser which made it easy to clean up a page before printing it out and was the obvious choice for quick word processing. Not to mention needing to install a mail application separately. Seems everyone forgot the lessons Netscape taught us back in the 90s.
And Chrome came along and claimed to be fast as well. Never mind it was an absolute monster, and only appeared to be faster because the UI was a separate thread that stayed responsive while heavy web-page processing was going on.
It seem fitting Firefox will flip the script and just pronounce itself the fastest.
