I think this is closer to being true, as someone who forks ff and has had to remove/add stuff and compile it myself for almost 5 years now.
I'm tempted to start working on adding native ipfs support for myself in netwerk/protocol/ipfs…
Hopefully uptake by non-mainstream browsers like Brave will increase the exposure, attract developers, increase the network and get us closer to having IPFS, Hypercore or some other protocol available to the mainstream, whether that be in Firefox or by some other means.
Besides, you could argue that browsers have added plenty of fad technologies over the past few years, DRM comes to mind.
TIL about hypercore! Looks like an interesting concept based on append-only logs. It reminds me of this work being done at VMware: https://github.com/vmware/node-replication
I don't think that is ever going to happen.
None of the reasons really sheds a good like on Mozilla.
