Well respected? In earlier times for sure. But Mozilla of today has totally left power users alone. I would not call that what is left a genuinely good company
I disagree about power users to a small extent. Rust has to be one of the best things Mozilla has ever been involved in. Servo looks really promising. e10s has actually worked out and Web Extensions will finally make addons secure. It's not an easy path or transition. Constantly modernising such an old codebase is a huge challenge I don't envy. I think the criticism levelled at Mozilla is too harsh some times. They've taken risks and sometimes it doesn;t always work out, like FirefoxOS phones.
