Firebug showing "Debugger is already active" error message after update 1.6.0?

Question

After the last Firebug update 1.6.0 I keep getting this error message when debugging (under the "Script" tab):

Debugger is already active

The debugger is currently halted at a breakpoint on another page. Go to that page

Okay, but "Go to that page" doesn't bring me anywhere and I can't seem to debug anything. I only have a single instance of Firefox running, restarting it doesn't help the issue ... even uninstalling the add-on and reinstalling it doesn't do anything. Is there anyway to remove the breakpoints from the command line, what's going on here?

Edit: Going back to 1.5.x solves the problems, but even going up to 1.7.x alpha reproduces the problem, I'd file a bug report, but if I'm the only one experiencing it, it isn't much of a bug.

Answer 1

We believe that this problem is fixed for Firebug 1.6.1; 1.6.1b1 is available at http://getfirebug.com/releases/firebug

I'd really like to hear more bug reports on this particular problem. This is probably an extension conflict, so we need folks to post the result of url "about:support" so we can compare the lists or we need you to try installing Firebug in a new Firefox profile then adding extensions until you find the problem. (I doubt jQuery is involve or we would catch it in beta testing).

My workaround: go to profile directory and delete firebug/breakpoints.json.

Firebug 1.6.1 on Firefox 3.6.13 on MacOS 10.6. Tried disabling all other extensions and had no luck.
