As one might guess from my username, I run Firefox. I love it -- I have it customized just the way I like it.
I think if they focused on memory issues rather than wizbang new features, paired with getting android and iOS versions up to snuff, they could catch up, paired with a marketing campaign.
What is our goal here anyway? Does everyone need to use firefox? A year of "Firefox on the desktop?"
Some tools are niche -- used by craftmen. What are sysadmins and engineers but, at heart, craftsmen?
Anyways, in closing I think it's a good browser.
