If your problem with Chromium is about privacy, SRWare Iron browser is based on Chromium, where you get Blink and V8, without the privacy problems that concern you.
It is being based on Chrome, but customised heavily. Which includes taking out Google tracking. Go read their forums about it. It is still on version 1.0, but no doubt will tick a lot of your boxes.
Vivaldi is great - it carries on from where Opera 12 left off. It's already stable. Not too fast and no 'Off Road Mode' but still vee good.
I use Epiphany at work (linux box), no problems with it, does everything I need (webmail, wikipedia, dictionary, El Reg) not flashy, but easy and simple.
I can suggest PaleMoon. It's based on Firefox, but with all of the crap cut out of it.
Vivaldi has also been mentioned, while it's good it tends to hog resources. It did so in my case anyway.
Anything that can be used comfortly without a mouse?
