I’ve been a long time user and supporter of Firefox – through all of the pains and memory hogging years. Before that I swore by Netscape Navigator.
I dabbled for a short time with Rockmelt – good idea – but didn’t seem to have the execution and updates.
I’m now back to trying Chrome. It’s improved a lot.
For fairness – Internet Explorer 10 is actually pretty impressive too. The ONE THING that I miss is a plugin that does adblock. There is a paid option for IE9 – but nothing for IE10.
