Firstly, thanks to all the developers who have worked on Dev Tools and Firebug over the years. They’re obviously a big part of the daily work flow for a lot of people, including myself. I’ve recently made the switch from Firebug, and wanted to share the things I miss. Maybe there’s a way to do these things and I just haven’t found it? If there is please let me know!
One of my favourite features of Firebug was the ability to have it running but not open. The icon would change colour, and if there were any errors you got an error count on the icon itself. I now have to keep Dev Tools open, giving up screen real estate. To see errors I need to leave it on the console tab and keep an eye out for errors scrolling by between xhr log messages. (And I don’t want to change the log filter settings, but when I’ve tried this I don’t see any visual indication of what I’ve toggled in the filters.)
Sorry to gripe, I would’ve stayed with Firebug longer but the Firefox upgrade made it pretty clear it was time to switch.
