Steps to reproduce:

Not clear what happen. Just reporting the issue because there is a big blue "File Bug Report" under the the text "The Debugger panel has crashed."

I had just reloaded an add-on I am developing. There was an exception from one of the pages that gets reloaded when the add-on is reloaded. I hit the continue execution button in the debugger and then the debugger panel crashed.

Actual results:

TypeError: ids is undefined

Thanks for reporting Matthew!

The resource layer causing this issue has been removed in Bug 1748222 which released as part of
Firefox 101 which is Nightly right now. Could you try to download Firefox Nightly and test to see if you
still get the issue.

I don't have a clear way to reproduce the issue. I've been developing my BBO Helper add-on steadily since reporting this issue and have not encountered the problem again.

Thanks.
I'll close the issue. Feel free to reopen if you get the same issue.
