You can argue for or against `fixamo` as a command, but Mozilla's position seems to be that even documenting the ability to turn off restrictedDomains anywhere is not allowed.
Among other things they're asking the author to censor the command from his personal dotfile. That's not justifiable and makes me really disappointed in Mozilla.
The "personal dotfile" that's lives in the same repo as the extension and is recommended as an example in its documentation, and only documents these commends as "Add helper commands that Mozillians think make Firefox irredeemably insecure". If you want to signal to a reviewer you're not taking them seriously, that's the kind of thing to do when they ask you to remove code.
`fixamo` was first removed after an informal request via informal channels from someone on the Firefox security team. The comment wasn't intended as a jab at a reviewer who didn't exist at that time; I was just tickling myself as is my wont.
I'm sorry if it offended anyone. I'm generally really appreciative of the work reviewers do.
