@blazorthon : I was sure that the browser is the browser is the browser... I mean, it's a browser, it comes from Mozilla, it uses the same rendering engine, the same script engine, the same GUI engine albeit with a different icon set and is not weighted down with functionalities... Which were optional in the Mozilla suite anyway. It looks like a bird, it flies like a bird, it squeaks like a bird, it lays eggs like a bird and it is named like a bird... But it's not a bird?
If we follow your logic, Internet Explorer is not 10 years old, since it was renamed 'Windows Internet Explorer' for version 7 and came alone while previous versions were 'Microsoft Internet Explorer' and came with Outlook Express, Windows Media Player, and MSN Messenger included in the installer - as such, of all current browsers, only Opera is more than 10 years old! Even though Opera 6 has very little in common with Opera 12.
Horse manure. For having tinkered with rendering engines ever since 'Webkit' was still named 'KHTML+KJS, Apple branch', Gecko is the current rendering engine+script interpreter that changed the least (it did get several overhauls) since it came out.
