They're not ridiculing him. It's natural and desirable for developers to be curious about other developers' setup.

I agree Chrome has never made lots of tabs easy. Since I'm usually signing into multiple accounts, I have several windows open anyway, so don't feel the pain as much as I used to.

I find this point and the XHR annoyance not enough to sway me though. Devtools keeps getting insanely more powerful to the point where front-ends will probably be using it as a proper IDE in a couple of years.
