问题
When I set a breakpoint with Firebug 2.0 in Firefox 30, I can't seem to set breakpoints using the line numbers column. It just throws up a spinner instead of the red circle.
Is there some new configuration option or something else that I am missing? Do I have to execute my code for the breakpoint to take effect?

This sounds like a bug in Firebug 2.0, which you should report in the Firebug issue tracker, so the team behind Firebug can fix it.
Before you do this you should follow the steps described on the first aid page for Firebug to track the issue further down. These steps are (copied from the first aid page):
- Open the Firefox Error Console (Ctrl/⌘+Shift+J). Any errors related to Firebug? Copy them and remember to include them in your report.
- Create a new profile, install Firebug, reproduce the problem. Still a bug? Report the problem, else
- Return to your previous profile, open the Add-ons Manager via Firefox menu bar > Tools > Add-ons, Firefox menu button > Add-ons or
about:addonsto disable all extensions except Firebug. Solved? Enable the other extensions again one by one until you find the buggy one and report it, else - Open the Troubleshooting Information via Firefox menu button > ? > Troubleshooting Information, click Open Containing Folder, open
prefs.jsin a text editor, copy all lines containingextensions.firebuginto a separate text file, reset all options (via the Firebug icon menu in the upper left corner of Firebug) > Options > Reset All Firebug Options, reproduce the problem. Solved? Report the problem attaching the created file, else - In the profile folder go to firebug/, move the file breakpoints.json (if it doesn't exist, go to step 4) out of that folder, reproduce the problem. Solved? Report the problem attaching your breakpoints.json (Attention: breakpoints.json contains the URLs of all breakpoints you set, so make sure there's nothing that shouldn't be public), else
- In the profile folder under firebug/ move the file annotations.json (if it doesn't exist, go to step 5) out of that folder, reproduce the problem. Solved? Report the problem attaching your annotations.json (Attention: annotations.json contains the URLs of all pages you enabled Firebug for, so make sure there's nothing that shouldn't be public)
