The Browser Version War

Today an alert on my computer caught my attention. The release of Firefox 17.0. The Browser version number WAR as described here.
I decide to check the last chrome versio and it is 23.0 and IE is 10.0

 Several years ago, in Brazil, we have a big inflation rate and the government divide the money by 10 or 100 to reduce zeros and launch a new money.

So Firefox is 1.7, Chrome is 2.3 and IE is 1.0 the initial version :-).
