it does suck, however, that things like this (and the dreadful new search box, the new tab bullshit, etc) are forced on people who then have to figure out how to get rid of the shit or revert to the 'old way', which often means digging into about:config or adding a new third-party extension because they take so much control out of the options UI
Too much in the UI was confusing and un-usable for the average person. From a UX point of view, it was a nightmare. From a support angle, it was terrible. People do not care about control, just the minute people like you'd find here. At least Mozilla is not like almost all open source companies where UX and UI is given no thought because developers design them as they think they should be, not how they should be. Hats off to Mozilla for doing proper usability studies, which Google copied Mozilla's conclusions to make Chrome UI.
