I agree with the developer tools take, they are sometimes unresponsive and difficult to read or analyse, especially snapshots.

Now, I have to disagree about the web standards, all major current browsers are W3C compliant, and developing under those guidelines is an interchangeable operation between browsers.

But of course, this a market, and browsers will one-up one another for a higher market share. Google for example has been pushing forward almost a new set of guidelines for Chrome, which has a gigantic market share; and those, while widely used, are not the norm, they should be namespaces, we as developers are bound to have to deal with these edge cases unfortunately.

I understand where the frustration is coming from, Mozilla isn't a saint, but with the current state of browsers, you can't possibly say that Firefox is a bad choice, overall It does everything a modern browser is supposed to do.

I'd even say it's a better option now than It has ever been.
