Funny how it seems no project ever gets it right when they change their interface. the complaints aren't exclusive to Firefox which says to me that people who claim to be tech ninjas might not be as good as they think with computers if all they go on to operate the thing is pure memorisation of the location of things.
So let's say it looks more like Chrome and that makes it worse. So the solution is to move to chrome? That makes no sense.
The biggest thing it did that might make it looks like Chrome is making it's tabs look more like folder tabs which is hardly exclusive to Chrome and it's minimised the space above the tabs. Boo hoo, it still has far superior extension support, superior handling of badly formed HTML, fails less frequently on shoddy JS and uses less system resources. Chrome has always used more resources but the google way of doing it was to make things feel more smooth so you don't realise it's pigging up more resource than IE or Firefox. Unfortunately for them everyone else is catching up on that idea and they're more efficient to begin with.
I don't mind their minimising either because unlike Chrome they don't enforce their minimalist design on you. It's still far more flexible and it doesn't do dumb things like force minimalism then put a big ugly download progress bar at the bottom of the window. So all in all it's still the superior product.
