> its developer tools are terrible compared to chrome. If you have the network console open while a large page loads, good luck interacting with the chrome until it's finished.

The only annoyance I have with the developer console is something they only recently added: you now need to right click in the console and tick "Log request and response bodies" every single time. No about:config option. But aside from that, I never noticed much difference. There are some things I like in Firefox that I missed in Chrome but that's probably because I'm used to Firefox. When I went the other way around, going from Chrome to Firefox after a few months of Chrome usage, Firefox had actually caught up and I didn't need Firebug anymore at all. Never noticed anything missing.
