Firefox may or may not have reset some of the LLM-related about:config preferences on me in a recent update¹, so I finally got around to locking them down with an "enterprise policy", per https://electric.marf.space/@trysdyn/statuses/01JN7H07704Z9ZJY197A9AM33K
Now I never have to worry about this again.
¹ Firefox can wipe out user-set preferences if they change their default preference value to your value in one version and then change it to another value in another version. User prefs vanish if they're set to the default.
