I have no source code. That was the error when I tried to build Firefox using the FreeBSD ports. The message asked for a bug report so that's what I did.

Thanks for reporting. This looks similar to #66487, which was patched in #66669 . The next nightly might work for you.

[jonas-schievink]

Closing as a duplicate of #66487. Please let us know if this still happens on the current nightly.
