this is the biggest blocker for me. i still use ff as my main browser, but i cannot develop with it, so i have to spend a lot of my time in chrome.

we had a recent dialog about it here:

there's some cool stuff in the works but it doesnt sound like there's a plan to internalize the work into devtools but to keep it as a web app and rely on a serviceworker for "localness" - not great, imo.
