Firebug won't delete a breakpoint

I kept running into this issue where Firebug 1.8.3 in FireFox 6.0.2 was not removing my breakpoints.  It removed the red dot, but continued to break at that line of javascript code anyway.  Even "Remove all breakpoints" did not help.  I found something that DID help.  You need to find and rename/remove your breakpoints.json file while Firefox is closed.  Mine is located here (Windows 7):

C:\Users\me\AppData\Roaming\Mozilla\Firefox\Profiles\2ziq4yrx.default\firebug\breakpoints.json
