I set the break point as directed, but it is not stopping code execution. When I look at the breakpoint in the breakpoint list it is labeled as undefined. I also note that the other lines of javascript in the function writeTimesTable() are numbered in green, the lines in the script that calls the function are not in green.

I have been searching online for a solution to this and the general discussion seems centered around proper activation of FireBug, and reloading the script. I have tried many times to follow those suggestions, no luck.

I'm having the same problem, breakpoints in the script that are in the document title block work (lines marked green in firebug), but ones in the body part of the document do not, and those are not marked green by firebug either.

Firefox 16.0.2 and firebug 1.10.6.
