@JohnPhilpin I've just worked it out — there's an extension, made by Mozilla, that automatically contains Facebook. The effect is that it breaks Threads, since Mozilla have yet to update it to automatically switch Threads into the container.

This is one of those situations in which Mozilla has an admirable goal but the execution is lacking.
