> Is it? That’s not a given, and we definitely can’t say either way yet. Considering all of Mozilla’s past efforts, pretty much all of which they abandoned, I’d be very wary of calling this one a success so early on.

The economics of selling branded clothing has been very well understood for 50 years. The markup for slapping a logo on a T-shirt is massive. Plus, it's a form of crowdsourced, word-of-chest advertising.

And Mozilla already has designers on staff. It's unlikely they had to do any extra hiring for this.

None of that addresses the point that the old logo was already very merchandisable.

Furthermore, whatever markup they’re making is not something you can just generalise. It is very possible, likely even, that the bulk of the cost goes to whatever company is making the t-shirts (I haven’t looked but I doubt Mozilla is doing it in-house).
