Citation, please. I'm a Mozilla employee, and was a Mozilla employee at the time. I'm not going to claim everyone was ecstatic about things; there was a lot of soul-searching going on for some people. But I don't recall any "Mozilla employees", in the sense of people working for the Mozilla Corporation, saying they would resign, nor calling for Brendan to do so.

There _were_ a few such calls from interns, and a few employees, at the Mozilla Foundation. People who were not involved in Firefox in any way, did not know Brendan, and were not relevant to the things that Mozilla is actually known for doing.

Of course the press spun the story in such a way as to make it seem like there was mass unhappiness internally... And most people read the press spin, not the actual blog posts actual Mozilla employees were writing at the time.
