Firefox 2.0.0.7 has a very serious calculation bug
From: "carl hardwick" <hardwick.carl () gmail com>

There's a flaw in Firefox 2.0.0.7 allows javascript to execute wrong
subtractions.

PoC concept here:
javascript:5.2-0.1
(copy this code into address bar)

Firefox 2.0.0.7 result: 5.1000000000000005 (WRONG!)
Internet Explorer 7 result: 5.1 (OK)
