I’ve resorted to only using Firefox for heavy front-end web development, and that’s only because Firebug is far superior to webkit’s built-in Developer Tools panel. They do the same thing, just Firebug is more responsive and, well, it just works better. Can’t really say more than that.
But otherwise, I think Firefox is a slow, lumbering old bear that is frankly a pain to launch and use. Every time I go to open it, it’s almost painful. I cringe a little when I go to it. That makes me feel bad because once upon a time it was really, really great.
It’s like a boyfriend you dumped who works at your favorite coffee shop. You hate to have to run into him sometimes, but you really, really love the coffee, and the knock-off coffee down the block isn’t good enough. So you bite the bullet and go in, and cope with the awkwardness.
It’s like that. Not that I would know. I hate coffee.
