They were extremely bullish with the database project when they wanted to use the name for their browser. They were of course backed by the huge AOL legal team at the time and did not shy away from using it.
Without diminishing the hard work the developers have put in to build a decent browser, I am and always will be sceptical about Mozilla. I think something happened to their culture during the AOL era and it's just not the same organization anymore.
I have sympathy for the database project too. Unfortunately I didn't get a chance to use it.
