Firefox Beta 3

Firefox 3 Beta 3 is out.

Almost 1300 modifications since the previous beta version.

... but the reason I'm really talking about it today is that: after facing a computer crash yesterday (which is not that common, to be honest, with my computer having uptimes of several months between reboots) I faced something I never experienced before:
When I restarted Firefox after booting, it was like it it was running for the first time. All my bookmarks were gone, it asked me again for all the "security" sending things over the internet, etc.

I know there are a lot of ways to keep my bookmarks safe (Google Toolbar, and others) but that's beside the point.

To make things "worse", in the FF 3 changes I see:

• Reliability: A user's bookmarks, history, cookies, and preferences are now stored in a transactionally secure database format which will prevent data loss even if their system crashes.

I have nothing against improving software, but... isn't this the kind of thing that should have been thought of right from the start?

I'm not arguing about other browsers being better or worse, again that's not the issue.
As a programmer, when I code something, besides making sure the program works as intended, I also try to anticipate all possible catastrophic scenarios that might cause my program to corrupt data, including computer crashes. Most programs I code must be (as much as possible) crash-proof, and able to withstand someone turning off the power at any time.

It seems that such concerns don't seem to worry many other programmers out there...
