Edit: As @bdonvr@thelemmy.club points out below

  1. This is just a mascot and is not a new logo
  2. The blog referencing Mozilla’s statement on the mascots gender says, (he/she/they/them/it), use whatever pronoun you prefer.

        Firefox is another name for the red panda, but the Firefox browser has always used foxes as logo/mascots. Before that it was called Phoenix, maybe that’s why they decided to just use another fire-related animal name without thinking about it too much.
