Mozilla is [1]exiting the fediverse by [2]shutting down its Mozilla.social Mastodon server on December 17 . Moving forward, the company will focus on Firefox and AI, aligning with its strategy under interim CEO Laura Chambers to scale back investments in non-core products. TechCrunch reports:

> Mozilla.social was a small instance, having only 270 active users at the time of Tuesday's announcement. By comparison, the most popular Mastodon instance, Mastodon.social, has over 247,500 monthly active users. Mozilla had telegraphed its plans to scale back on its fediverse investments earlier this year after the CEO stepped down. At the time, Mozilla board member Laura Chambers took over the job as the interim CEO of Mozilla Corporation through the end of 2024. Shortly after the change in leadership, Mozilla said it would refocus its product strategy around Firefox and AI and significantly scale back or even shutter other efforts. Among those products affected by the pullback were its VPN, Relay, and Online Footprint Scrubber, in addition to its Mastodon instance, the company said at the time. Meanwhile, its virtual world Hubs was shut down.

> The redirection of Mozilla's efforts came after its flagship product, the Firefox web browser, spent years losing market share. That left room for other competitors, like the startup Arc, to take hold in the alternative browser market. Months prior to this change in strategy, Mozilla had been touting the fediverse's potential, but under Chambers, the company said that a more "modest approach" to the fediverse would have allowed it to participate with "greater agility." In an internal memo, Mozilla signaled that going forward, a "much smaller team" would participate in the Mastodon ecosystem. However, it didn't say at the time that the Mozilla.social instance would shut down, adding that it would continue to bring small experiments to those who participated on its instance.

Mozilla said it was a "hard decision."
