Yeah, considering how poorly it went and how much market share they lost I also always thought it was outrageous... Also so many people laid off and projects shut down. I don't have any insight, and I could be way off, but it always felt like the company was captured by bureaucracy and drained as long as it was possible. Again I could be way off, as I don't have any personal connections to it. I was a regular user until around 10 years ago, but Chrome just leapfrogged them and that was it. There was at one point nothing left other than nostalgia.

edit: I still remember using Mozilla which was this "good thing" but somehow clunky, and then getting so excited when trying Phoenix for the first time, which was then renamed to Firebird, and lastly Firefox. It was so "obviously" the right thing to use.
