I hear yah. I just switched all the public computers in the library I run over to Pale Moon, after hearing yet another patron complain that "Firefox is broken!" A large proportion of the users here laboriously learned to use a computer and rely on careful repetition of the steps they memorized to access email or other simple tasks. Suddenly, the back button is in the wrong place, the tabs are on top, the progress bar is gone and so is their weather! They can't cope with the changes, and aren't savvy enough to be able to figure them out on their own.
So, after years of evangelizing Firefox, I find myself saying, "Just click on that little moon there; and they click; AND IT JUST WORKS LIKE FIREFOX.
Honestly, dev-folks--Unity, Australis, Gimp2.8 (File>>Save!!), etc.--don't you want us to spread the gospel of F/LOSS? Why do you have against average users? --or solid, functional user interfaces THAT ANYONE CAN USE?
Sorry. I guess I'm getting tired of being shot in the foot by my own side.
