The technology is what matters to users. Mozilla only matters in that they develop and publish the software that users care about.
If the software is forked and development is continued as an open source project under the auspices of another organization, that works just as well for users. Conversely, if the software dies but the Mozilla Corporation survives as the world's leading manufacturer of paperclips, that's of no value to the software's users.
