There's a bug in FireBug: I accidentally clicked where the line numbers are, which sets a breakpoint. So I clicked again to remove it. Now it's breaking there every single time. And I've tried setting/removing a breakpoint, but it doesn't work. I've even tried clicking the pause icon, which I see suggested elsewhere, but it does nothing -- it doesn't even change. I've even tried setting it to be a conditional breakpoint that is always false so it should never fire. No cigar. I even tried uninstalling FireBug and reinstalling it!

(Please note that I am using FireBug 1.7.3 with FireFox 3.6.25, and have to for a reason, and cannot upgrade.)

[I'd post an image, but I cannot until I have 10 rep pts!]

How can I remove all breakpoints? Do I have to uninstall / reinstall?

Try this:

  • In Firefox, go to URL about:support
  • Check the Profile Directory
  • Open containing folder
  • Go into folder firebug
  • Delete breakpoints.json

      You can "accept" the answer, though, by clicking on the green 'tick'. – Dawood Feb 01 '12 at 05:52

      Same symptom showed up in firebug 2.0.1 firefox 30.0; same basic solution still applies. It didn't work the first time so I added some steps: disable firebug, exit firefox, delete the file, restart and reenable. (Maybe only one of those extra steps was really necessary, but I don't know which.) The weird part is I looked in the file and it contained only one entry, referring to a completely different site. –  Jun 24 '14 at 13:37

    I am having the same issue with Firefox 79.0. Since the breakpoints.json does not exist anymore in this version (how does firebug keep track of its breakpoints now?), I tried

    • In Firefox, go to URL about:support
    • Click "Refresh Firefox"

    This resets everything to default (language etc.) but also removed "ghost breakpoints".

    I think I managed to fix this for newer Firefox versions, that, as was mentioned above, don't have the breakpoints.json anymore.

    • Open the Profile folder
    • Navigate to the storage\permanent folder
    • Close Firefox
    • Delete the indexeddb+++fx-devtools folder

    The deleted folder will be generated again, so don't worry.

    You'll probably lose some configuration on the devtools, but it's better than refreshing your entire browser.
