Different shape and color guess I makes it, but they should mention it in the guidelines.
It's a good thing I think that they are spending time helping people. It is developers within Mozilla who are answering the questions so hopefully they will take notice of what is confusing and troublesome for people and use it to fix the concentrated areas.

"A note on the dino"
"The classic Mozilla dino head logo served as a symbol of the organization since our earliest days, but has now been retired from active duty. While the brand has evolved, the dino had not been updated in quite some time and is no longer the best representation of who we are today. He spends his days traveling, reading and still looking out for the interests of users everywhere (some habits die hard). We wish him well in his future endeavors. Please use the Mozilla wordmark on all properties and materials instead." - https://www.mozilla.org/en-US/styleguide/identity/mozilla/br...
And exactly, we both want to help out and also identify what developers have issues with.
