The current Mozilla might disappear but if it brings back the old Mozilla it can only be a good news
Then thank god that Firefox is FOSS, so whoever picks it up won't have to. The abolition of Mozilla would mean that more thoughtful forks won't have to compete with upstream for either cash or attention. Although I'd bet $1000 that if Mozilla died, they'd give Firefox and its trademarks to the Apache Foundation Openoffice-style to protect Chrome even after the company's last breath.
