Firefox died long ago.

It was an engine fight, and Mozilla decided not to participate.

Is there some reason that wall won’t work fine?

You’re the asshole to the normal extent that anyone who makes an excuse to skip a party is an asshole.

That being said, a party thrown by someone who is trying to be conspicuously wealthy is an excuse to drink for free, so skipping it is kind of lame.

I’ve got a couple VPSes, hosting

• Mailcow, because email is identity.
• Asterisk, because phone #s are also identity.
• Matrix-Synapse, for personal messaging even though XMPP is probably better.
• ttrss, even though it’s junk software with a jerk developer.
• A bunch of self-developed web apps

Self hosting email is obnoxious, but it’s also one of the only remnants of the traditional distributed internet that’s still broadly accepted.
