User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:11.0) Gecko/20100101 Firefox/11.0 Build ID: 20120310010316 Steps to reproduce: While debugging an issue in some of my JS code, I found an odd behavior when performing tests on a null value. Apparently null values are not equal to zero, and are not greater than zero, yet somehow ARE greater than or equal to zero. The problem first presented itself in my JS code; I investigated further using Firebug. Actual results: null == 0 (false) null > 0 (false) null >= 0 (true !!!!!!) Expected results: null == 0 (false) null > 0 (false) null >= 0 (false)

Bugzilla is not there to answer questions. A good start is it to compare different Javascript Engines in the differen browsers (IE, Opera, webkit, gecko) Different results in different Engines are usually a bug and filing a bug in that case is good idea. http://stackoverflow.com/questions/2910495/why-null-0-but-not-null-0 should explain this is no bug.
