Firebug 1.2 beta for Firefox 3 RC 1

Category: Debugging, Firefox

Firebug 1.2 beta is in the wild. The latest beta of the bug your FF3RC will love features:

Enablement UI

  • Disable always: when the Firebug UI is not active on any page, the debugger is disabled (minimal overhead)
  • Instant on: when the Firebug UI is active, HTML, CSS, DOM views activate (minimal overhead)
  • Script panel user-activation: initially disabled or enabled always
  • Net panel user-activiation: initially disabled or enabled always
  • Bug Icon gray unless some page has Script or Net panel activation
  • No Allowed-sites/Disable for Site: no longer needed. The UI for this feature is being refined; overhead tests have not been completed. We are interested in feedback on this UI change.
    Javascript Debugging

  • Written/cleaned up eval support
  • Performance on eval better, easier to support. This feature is complete; Bug reports on javascript debugger welcome.
    Net Panel

  • Net timing more accurate
  • Only real network requests displayed.
  • Limit for number of requests (configurable in preferences).
  • Additional columns for: request method, status response + text
  • Cache tab has expiration time in Net panel

  • Redesigned to use events/attribute passing.
    tests/console/joes-original/test.html mostly passes
    Command Line

  • Redesigned to avoid using evalInSandbox.
    tests/console/commandLineObjects.html mostly passes
    commandLineAPI functions, ok.
    DOM Panel

  • Works for FF3pre after about 2008041406 (

Bug away!

Simon Willison also recently pointed out the command line API that lets you “set a breakpoint at the start of a function with “debug(fn)” and log all calls to it with “monitor(fn)”.”

Great news I was facing some problem with FireBug 1.1 on FF3RC1.

It would be very helpful if JSON in the Console/Response tab were formatted – pretty printed

Yes Firebug 1.1 has had a console security bug which started manifesting in FF3b5. But the reasons to upgrade to 1.2 go way beyond that. Firebug 1.2 is killer!

Does console.trace work yet?

Did they fix the bug where it would disable your tab and enter key if you do too much css editing?

I’m not sure if I want to even upgrade since YSlow breaks it right now…that should be something Y! and the FireBug developers need to work on ASAP!

The tab and enter key bug, especially prevalent on the Mac, is the Achilles’ heel of Firebug. Let’s hope it’s resolved in FF3! I’d rather have Firebug than my tab and enter keys but hopefully I won’t have to make that choice!
