Yes, Chrome is fine on that regard since Google had the wisdom to introduce extensions early on, instead of Opera for example. But Firefox is so much better since there are addons for virtually everything. Don't like the default cookie or download managers, or the status bar? You can just swap them for better ones. NoScript adds a layer of protection beyond a simple JavaScript whitelist that's yet to be seen on other browsers. Obscure things like handling redirects based on regular expressions, or blocking cache tracking can also be done.
As for the element inspector, all major browsers have one nowadays. It's essential for testing the compatibility, appearance and security of pages, as well as useful for those who like to tinker with stuff. You can use it to test new styles, edit or remove elements you don't want to print, evade some "soft" limitations as in your case and send raw HTTP requests, among many other things.
