Uhmm... I am using both chromium and firefox, Firefox Dev Tools is superior imho.. I can't graps something like network stack freely or DOM checker freely in Chromium... so... I don't think it's bad, rather than bad, it's great for me for professional works.
Yeah... they still haven't added back live editing of JS. Their new profiler doesn't provide framerate graphs anymore. Nothing like Lighthouse on offer. Gotta keep a Chrome-based browser around for any non-trivial frontend work.
