I’m using FirefoxDeveloperEdition 57.0b5 and frequently see slow/unresponsive behavior when developer tools are open. It can take me 10+ seconds to inspect and element and get over to the react devtools tab. I also frequently see beachballs and slowness when I drop a
debugger breakpoint into my app, and often times the top half of the debugger window that shows the code above the console doesn’t even appear and I have to refresh/try again.
I tried disabling all my add-ons (including react devtools) and see the same behavior. I’m very happy with Firefox for browsing but I don’t experience these issues in Chrome and they’re significantly slowing my workflow. Has anyone else experienced this?
