Mozilla firefox. I am not a techy but I noticed that it is easier to browse, opens pages quickly, the commands/buttons are easier to find and master and it directs you to the intended sites most of the time
Mostly chrome, occasionally firefox if chrome is having a tantrum. Safari on the phone. x)
I love chrome - it's just so simple. I used to adore firefox, but there's just too much faff with it - add on this, add on that, update this add on, firefox is updating, firefox is being a royal pain in the arse.
Chrome is just so very clean, simple and fast.
I'm one of the very few that say they use Opera. Opera's my main browser... but I use different browsers for different things... like Safari's my homework/school browser and Firefox is my uni app process browser. It's a bit weird I guess...
