I'd think by your UID you'd have been around long enough to recognize this pattern.
This is just how Netscape manages itself into ... well not being in business. Just because they changed their name to Mozilla after Sun realized how shitty they were doesn't mean its a different company really.
Netscape has never had a grasp on what their customers wanted or needed. They have always coded themselves right out of existence by doing stupid shit JUST like this. No one at Netscape that makes decisions should be allowed to make decisions, they repeatedly show no clue who their target market is or what that market wants and then tell that market both things regardless of the fact that people WHY more qualified than them are part of their target.
You know why we have Google Chrome? Because Netscape (the company) is fucking stupid and Google knows it. They like to make decisions based on principals ... and they're stupid principles that no one gives a fuck about outside of their tiny little over funded for no reason world.
I call them netscape because its the same people making the same stupid decisions that put them out of business the first time around, and some of those people went on to Sun ... and helped put them out of business as well. They make decisions for their own personal purposes. They don't deserve to have a business, but a bunch of techies fanboy'd up on firefox because 'its not Internet Explorer' ... not because its a good browser, its about the shittiest browser used on the web today in every way. That legacy still keeps random fanboys ranting and raving about how theres nothing wrong with firefox and random UI and code changes weekly are the way everything should be done.
God, I can not explain in enough detail how horrible Netscape/Mozilla is at software development. Without their anti-Microsoft fanboys, they wouldn't exist, and even thats going away.
When Adobe's PDF reader is less of a resource hog than your browser, you probably fucked up ... A LOT.
