Thanks for your work on Firefox!
I feel more comfortable with Firefox Devtools overall, but I keep using Chrome for debugging for one single reason : Firefox can't handle extensive log.
I'm working on code where sometimes infinite loops occurs. When I want to investigate on these loops, I cannot use any breakpoints because it's using the same route than it used 10 000 times before, so I usually log a lot of data, then manually kill the Chrome tab and I can still run through 1 million console lines smoothly.
Really hope Firefox will be able to handle that one day.
