Discontinue compatibility overrides (original) (raw)

We introduced compatibility overrides along with "compatible by default" extensions, many years ago. Since WebExtensions, this feature has become unnecessary, and legacy add-ons are long gone. We can start removing this feature, returning an empty response so clients don't break. Requests from Firefox will eventually go away, but it'll be a while.

@wagnerand pointed out a few overrides that might still be relevant. I investigated them and determined they won't be a problem.
