She's straight, married, one son. So whatever she did, she did out of Berkeley moral arrogance or pressure from "somewhere".
I seriously doubt she needed the least bit of "pressure" to do what comes naturally to Berzerkerly grads when blood is in the water. I seriously doubt she had the courage to oppose the "pressure" even if she wasn't naturally inclined to cut down anyone who isn't ideologically pure.
Firefox is essentially doomed anyway. It's become buggy and unstable and there are plenty of superior alternatives.
The last thing I was using it for was the SQLite Browser add-in tool, which I very occasionally use to support 2nd level support people who're having trouble with one of my mobile apps. I knocked off a C# version of my own that does the same thing last night, and uninstalled Firefox on all of my real machines and VM's this morning, and I'm advising my 1st and 2nd level support people to do the same.
