Mozilla’s trademark policies have been annoying enough in the past that Debian used to ship a fork with the branding stripped. Hyperbola continued this practice for a while, but stopped for a variety of reasons in the It’s Foss interview, and switched to a UXP-based browser. I’m writing this from a UXP-based browser because I find it much better than Firefox and I dislike Mozilla in general for more than one reason.

But no, there are other reasons outside of trademarks, some technical ones are in submisson’s article.
