Comment Conentrate on the browser part (Score 5, Insightful) 320
I love Firefox and use it every day, but I'm getting a little tired and confused with some of the features they keep putting into the core. I've always thought one of the great things about Firefox is the extensions; and while other browsers offer similar 'add-on' concepts, Firefox just seems to do it better. Why aren't they concentrating on just making a seriously good browser engine and then leaving the extra stuff to the extension developers. Or, if it's something important, get with the extension developers and help them out, offer a 'Firefox suggested extension package' that downloads and enables extensions by default. That way, all the 'normal' users get the cool goodies, and the rest of us can turn them off or uninstall them all together if it's not something we need.
For instance, the new development centric stuff they have in FF13 is nice. But it doesn't hold a candle to the development tools that have been in IE9 and Chrome for some time. I use Firebug for all my web debugging needs in FF and it works wonderfully. Get with those guys and improve their already awesome extension. Don't try to re-invent every cool extension and add it to the core. Not everyone needs it, not everyone wants it. Just build the fastest, most standards compliant browser out there that offers an amazing extension engine and you'll have a winning browser.
