Which type of founder would voluntarily resign from the CEO position at his own company? (esp. a project like Mozilla) Eich resigned under huge pressure after the media broke the story and ran with it for days.

I started an internship at Mozilla right when Eich got fired, and the vast majority of people I talked had the same reaction: "Yeah, his donation isn't bad in itself, but the way he dealt with this polemic shows he's a bad as a CEO" (which does not convince me at all... since, you know, nobody is ready to deal with that type of pressure from the media, unless you're a politician with a PR team).

Bottom-line: As a CTO, he had a lot of engineers reporting to him, many of which were LGBTQ, and Mozilla is known for being one of the most pro-LGBTQ companies out there. He would have most likely been a great CEO to Mozilla, and a donation done personally cannot possibly be a valid reason for asking him to resign (the media, a tiny minority of people at Mozilla).

No. A C level officer is part of the public face of the organization. If one can't handle the binding of their personal life to that face, they should step down.

Great, that's what happened and now FF is in worst shape than ever. Anecdotally, I used to love FF but for the first time since the first released version of FF it is not my default browser anymore. Too much issues, I could not handle my frustration anymore. The silver lining may be Servo, I don't know, but at least I don't see a bright future with this current code base.
