Ah yes, the toolchain changes appear to be a stumbling stone for the Fennec devs as well. That kind of thing doesn’t exactly speed up new releases, I’m sure.

What are your experiences with Mull? Is it generally compatible with Firefox plugins, and are there performance improvements as well as in security?

There’s another reason I don’t share “It’s FOSS” links anywhere: this should have been a github issue but it’s turned into a clickbaity headline. Every othe article coming out of “It’s FOSS” is either low effort, sensationalist, or both.

The answer is one click away in their FAQ:

Why do you charge for attendance?

Several reasons:

• Organizing conferences costs time and money, like many other things in the Fediverse. We believe the sooner the Fediverse finds a way to pay for itself that doesn’t depend on the heroic efforts of a small number of individuals, the better. We want to build something that is sustainable, and to do that, it needs to know how to pay for itself.
• It aligns the objectives between organizers and attendees, and keeps us organizers focused on what you want out of the conference; as opposed to us pushing an agenda, or letting a sponsor undule influence the agenda.
• In our long experience organizing conferences we have learned that people who pay for an event are much more likely to actually attend. Free-of-charge conferences often have more no-show’s then actual attendees.
